The gastro-intestinal parasites community of the Przewalski's horse, Equus przewalskii Poljakov, 1881, and the domestic horse in the Chernobyl exclusion zone.

A diagnostic deworming of 21 Przewalski horses, free-living in the Chernobyl exclusion zone Ukraine, and of six stabled domestic horses, has been conducted eighteen years after the Chernobyl nuclear disaster. This survey yielded 31 species (of 5 families and 3 classes, 28 species of nematodes, 1 species of cestodes, and 2 larvae of botflies). A total 29 and 19 helmith species has been recorded in the Przewalski horse and domestic horse respectively. Only six helmith species were common for the two horse species. Species from the family Strongylidae constituted the dominant helmith group. Four cyathostomine species (Cyathostomum catinatum, Cylicostephanus minutes, C. longibursatus, Cylicocyclus nassatus) formed the majority of helmith parasites both in the Przewalski and domestic horses. The presently reported study revealed that Przewalski's horses keep their typical biological features and high resistance to parasitic infections. A substantial growth of heard was observed as well as good clinical health state of horses. This can be an argument favouring the use of Przewalski horses in re-naturalization of ecological disaster areas.

Genetic diversity in wild (Sus scrofa scrofa) and domestic (Sus scrofa domestica) pigs and their hybrids based on polymorphism of a fragment of the D-loop region in the mitochondrial DNA.

We examined the variation in mitochondrial DNA by sequencing the D-loop region in wild and domestic (large-white breed) pigs, in hybrids between domestic and wild pigs, and in Monteiro pigs. A D-loop fragment of approximately 330 bp was amplified by PCR. Sequencing of DNA amplicons identified haplotypes previously described as European and Asian types. Monteiro pigs and wild pigs had European haplotypes and domestic pigs had both European and Asian haplotypes.

Domestic violence among women attending out-patient clinics in Ain Shams University Hospitals, Cairo, Egypt.

Violence affects millions of women worldwide and it cuts across cultural and religious barriers, impeding the women's right to participate fully in the society. A descriptive cross sectional study was conducted to determine the prevalence of domestic violence among ever married females presenting to out patient clinics in Ain Shams university hospitals and to identify factors affecting it. Out of a total number of 509 women, 89.8% had experienced one or more episodes of violent behavior by their husbands of which 56%, 88.4% and 47.9% suffered physical, control and threat violence. Both univariate and multivariate analysis was done. The most common form of violence among the study group was husband's shouting followed by being kept short of money. About 34.2% had been beaten by their husbands and 17.1% were forced to do sex. Using multiple logistic regression it was found that smoking husband and economic problems were independent significant factors associated with all forms of violence. Suffering violence was significantly associated with different forms of health complaints and only 9.1% had been asked by their doctors on domestic violence exposure. This proposes the importance of effective screening, diagnosis and management of domestic violence victims.

Morphology of normal and osteochondrotic porcine articular-epiphyseal cartilage. A study in the domestic pig and minipig of wild hog ancestry.

Osteochondrosis is a generalized skeletal disorder that affects the growth cartilage in the growing domestic pig but not in the minipig of wild hog ancestry. In the present study, we compare the ultrastructure of the articular and epiphyseal growth cartilage in the domestic pig with that in the minipig. The domestic pigs had areas of enlarged epiphyseal cartilage with chondronecrosis, which had caused focal impairment of the endochondral ossification, with retention of cartilage in the subchondral bone. Areas of chondronecrosis close to blood vessels were found in the resting zone, with no evidence of thickened cartilage or impaired ossification. The chondronecrosis was surrounded by chondrocytes, organized in small clusters, containing many lipid droplets. The vascular channels adjacent to the chondronecrosis contained degenerated blood vessels. The minipigs showed no areas of enlarged epiphyseal cartilage. A few dead chondrocytes could be seen close to vascular channels which contained morphologically normal blood vessels. We conclude that restricted perivascular chondrolysis may occur in the pig without the presence of vascular degeneration and without progressing to osteochondrosis.

[Frequencies of mutant genes in two populations of domestic cats in southern Sakhalin].

Analyses of mutant gene frequencies have been completed for the domestic cat populations of cities Kholmsk and Juzhno-Sakhalinsk (Sakhalin isles). Mutant allele frequencies reported here differ from these of other Soviet Union populations of the tb and d loci. It is suggested that Sakhalin populations were influenced by domestic cat populations from East Asia. The genetic profile of the domestic cat of Sakhalin shows the close relationship with China populations. Furthermore, the results of the present study are very similar to those previously reported for Vladivostok and Khabarovsk. These similarity, perhaps, may be depend on their settlement history.

[Behaviour of domestic high gold alloys in telescoped crown systems].

A great variety of elements and systems have been used in prosthetic dentistry for retention of removable partial dentures. The aim of this paper was to examine the possibilities for retention of telescoped crowns with parallel axial planes, made from domestic alloys, and influence of these alloys on the crowns durability. Two domestic alloys, Platinijum MPa-20 and Dentor-S, were used. Comparison between Platinijum MPa-20 and Dentor-S, and the results related to Degulor-M alloy suggested the excellent quality of domestic alloys, which recommends them as suitable materials for these purposes.

[The Sertoli cell nucleolus in domestic and wild animals].

Sertoli cells produce special microenvironment for developing germ cells; therefore it is assumed that they play primary role in the onset and control of spermatogenesis. In this connection we extended our previous study on the ultrastructure of Sertoli cells in different domestic and wild animals with special regard to nucleolus. Sertoli cells of domestic and wild ruminants possess the typical vesicular nucleolus except for fallow deer, in this species no vesicular nucleolus occurs in Sertoli cells even during the rut. In roe.buck, another wild ruminant with seasonal spermatogenesis, cyclic changes were found in the nucleolus of Sertoli cells. If no spermatogenesis is present, the Sertoli cells have a reticular nucleolus. Membranous vesicles appear in the nucleolus of Sertoli cells of roe-buck at the onset of spermatogenesis 1-2 months before rut. In domestic ruminants with continuous spermatogenesis the vesicular nucleolus in Sertoli cells is present permanently. During postnatal development of bull and ram the vesicular nucleolus appears in Sertoli cells just before the onset of spermatogenesis. In experimental cryptorchidism of bulls a vesicular nucleolus is found in the Sertoli cells. Our observations and experiments support a hypothesis that Sertoli cells have primary role at the onset and the maintenance of spermatogenesis.

Determinants of domestic water use in rural Nicaragua.

In order to investigate the factors affecting domestic water use in rural areas of developing countries, an analysis was performed of water consumption estimates from 1029 different households in Nicaragua collected between May 1986 and December 1988. Eight of the 22 variables hypothesized to be related to per capita domestic water consumption, were included in the final multiple regression model. These were; household size, site of clothes washing, the type of water source, mother's and father's levels of schooling, distance to the water source, wealth, and ownership of cattle. According to this model, a decrease in the distance to the water source from 1000 to 10 m is associated with an increase in per capita water consumption of 20%. Similarly, families where the mother has 6 years of schooling use 17% more water than families where the mother has had no formal education. The same difference in the father's schooling is associated with 12% greater per capita water consumption. A better understanding of the factors affecting domestic water use is needed to improve the design of interventions aimed at reducing the transmission of water-washed disease in developing countries.

Police response to domestic violence: the influence of individual and familial factors.

Although police officers are often the first group outside the family to intervene in domestic violence situations, little is known about how individual and family characteristics influence the male police officer's responsiveness in these situations. This study addressed this issue with data from 72 midwestern male police officers. The officers were asked to respond to vignette scenarios in which husbands had assaulted their wives. Three variables previously related to spouse abuse (sex role egalitarianism, approval of marital violence, and marital stress) and the officer's use of violence in his own marriage were entered into a path model to predict three different possible police responses (i.e., mediating response, arrest, and antivictim response). The model predicted significant variance in the officer's hostile response to victims of domestic violence but not to his likelihood of arresting abusers or mediating between the abusive couple. Implications for understanding domestic violence and police response are presented.

Teratospermic and normospermic domestic cats: ejaculate traits, pituitary-gonadal hormones, and improvement of spermatozoal motility and morphology after swim-up processing.

Electroejaculate traits, testicular volume, and circulating FSH, LH, and testosterone concentrations were compared between two populations of domestic cats consistently producing either a high (greater than 60%, normospermic) or low (less than 40%, teratospermic) incidence of structurally normal spermatozoa/ejaculate. The effects of semen dilution in Biggers, Whitten and Whittingham (BWW) or modified Krebs Ringer bicarbonate (mKRB) medium and swim-up processing on sperm viability and duration of motility in vitro also were assessed. Ejaculate volume, percent sperm motility, sperm progressive motility, motile spermatozoa/ejaculate, testes volume, and mean serum FSH and LH concentrations were similar (P greater than 0.05) between normospermic and teratospermic cats. However, sperm concentration/ml of ejaculate was greater and circulating testosterone levels were lower in teratospermic males. Swim-up processing increased (P less than 0.05) percent sperm motility, progressive motility, and the number of structurally normal sperm cells recovered and also prolonged the duration of sperm motility in both cat populations. In teratospermic ejaculates, swim-up separation increased the proportion of morphologically normal spermatozoa recovered by more than two-fold. Diluting cat semen with either BWW or mKRB increased flagellar bending in both normospermic and teratospermic cats. The sperm motility characteristics of only the teratospermic ejaculates were influenced by medium type; mKRB increased percent sperm motility and progressive motility whereas BWW had no effect. Compared with undiluted raw ejaculates, the duration of sperm motility was improved 18- to 24-fold by diluting semen in either BWW or mKRB medium followed by swim-up processing. This study demonstrates that the electroejaculate characteristics of domestic cats vary markedly and that some males consistently produce high proportions of morphologically abnormal spermatozoa. Diminished serum testosterone concentrations and normal pituitary secretion of FSH and LH in teratospermic males suggest that there is an inverse relationship between gonadal androgen production and pleiomorphic spermatozoa in the domestic cat. The swim-up procedure is effective for recovering motile, structurally normal spermatozoa from teratospermic cats.

[Epidemiology of toxoplasmosis in Chile. V. Prevalence of the infection in humans and domestic and wild animals, studied by indirect hemagglutination reaction, in the Juan Fernández Archipelago. V Region].

A serological study utilizing an indirect hemagglutination test (IHAT) for toxoplasmosis was carried out in 222 humans and in 58 domestic animals (31 dogs, Canis familiaris; 27 cats, Felis catus), and in 62 wild mammals distributed into 50 rabbits, Oryctolagus cuniculus and 12 goats, Capra hircus. This survey was performed in the Juan Fernández Archipelago, formed by three islands: Robinson Crusoe, Santa Clara and Alejandro Selkirk (80 degrees 47'-78 degrees 47' west long., and 33 degrees 36'-33 degrees 47' south lat.). Blood samples were collected in filter paper and IHAT with titres greater than or equal to 1:16 were considered positive. This survey showed a prevalence of 42.3% in humans with no difference between men (43.0%) and women (41.5%). A high prevalence was found within groups of young individuals (0 to 19 years old), men and women. Regarding the domestic animal population, 44.8% resulted positive, distributed as follows: dogs 9.7% and cats 85.2%. Twenty one percent of wild animals were positive, distributed as follows: rabbits 8.0% and goats 75.0%. The global prevalence of toxoplasmosis in animals (domestic and wild) was 32.5%. All titres in humans and animals were less than or equal to 1:512. Toxoplasmosis is well extended among the human and animal population of the Juan Fernández Archipelago.

[Polyarteritis nodosa: general aspects and occurrence in domestic animals, particularly in association with nosematosis in blue foxex (author's transl)].

A survey of polyarteritis nodosa in domestic animals is presented, including a description of the patho-morphological lesions and a discussion on the causal factors. This vascular disease occurs in domestic animals in association with both viral infections (infectious plasmacytosis in mink), bacterial infections (erysipelas in swine), and protozoan infections (nosematosis in blue foxes). The conclusion is drawn that the observations in domestic animals support the view that immunological disturbances are involved as pathogenetic mechanisms. Nosematosis is dealt with in more detail; the infecting agent (fig. 1), Nosema cuniculi (Encephalitozoon cuniculi), is a widespread mamalian parasite, which causes cerebral and renal lesions in blue foxes of the same type as in animals of other species. In addition, the vascular system throughout the body is affected, resulting in patho-morphological alterations corresponding to classical polyarteritis nodosa (Fig. 2). In the early stages of involvement, masses of parasitic organisms are regularly found within the walls of affected arteries (Fig. 3). This disease is frequently lethal, and always accompanied by elevated values of gamma globulins. Both the hypergammaglobulinemia and the tissue lesions, seem at times, at least in part, to be reversible.

Assertiveness deficits and hostility in domestically violent men.

Two types of assertiveness, the ability to refuse a demand or request and the ability to initiate a request or affirmatively express a need, were examined in a clinical sample of domestically violent men (N = 78) in contrast to a nonviolent comparison group (N = 29). No significant difference was found between the groups on refusal behavior. However, a significant difference was found on initiating/request behavior, the violent men evidencing lower scores than their nonviolent counterparts. Significant differences in anger and hostility were also apparent between groups. There was a significant and positive correlation between refusal behavior and overt anger/hostility. A significant and negative correlation was observed between initiating/request behavior and covert anger/hostility. The results support the presence of social skill deficits, which appear to be significantly related to anger and hostility in domestically violent men. The findings also suggest that domestically violent men have a more specific profile of assertiveness deficits than has been previously discussed in the literature.

MMPI profile of women and men convicted of domestic homicide.

The present study investigated the psychological characteristics of men and women convicted of domestic homicide. Demographic information and MMPIs were collected from women (n = 16) and men (n = 20) convicted of murdering their partners and men (n = 19) convicted of murdering strangers during the course of a crime. Analyses of variance indicated that women had significantly higher elevations of MMPI scales PA and SI than both groups of men, while men convicted of murdering strangers had higher elevations on scale MA than men convicted of domestic murder. These findings suggest different patterns of psychopathology among homicide offenders depending on the offender's relationship to the victim. Results are discussed with reference to previous research on domestic murderers and female offenders.

Pesticide residue findings by the Luke method in domestic and imported foods and animal feeds for fiscal years 1982-1986.

Nearly 20,000 samples of food and feed commodities were analyzed for pesticide residues by the U.S. Food and Drug Administration Los Angeles District Laboratory during the 5-year study period 1981-1986. The resultant data base has been summarized to provide separate residue information for domestic and imported samples. The overall violation rates for domestic and imported samples collected on a surveillance basis were 3.0 and 2.6%, respectively. For domestic and imported samples collected on a compliance basis, the overall violation rates were 19.7 and 17.5%, respectively.

Trichinella spiralis in an agricultural ecosystem. II. Evidence for natural transmission of Trichinella spiralis spiralis from domestic swine to wildlife.

Epidemiological investigations of an outbreak of trichinellosis were carried out in a domestic swine herd and it was established that the parasite also occurred in rats, and in skunks, opossums, and raccoons. Because considerable uncertainty exists regarding the role of sylvatic trichinellosis as a reservoir for the synanthropic cycle, studies were conducted to determine the genetic nature of the various isolates from this ecosystem. Pig infectivity trials, isoenzyme analyses, and repetitive DNA sequence analyses were performed. The results showed that all isolates from the farm environs were genetically similar and that they are related to Trichinella spiralis isolated from domestic pigs. The implication of these findings, in contrast to studies on isolates from wildlife elsewhere, is that this parasite is transmitted from domestic swine to sylvatic hosts and that any control or eradication efforts must take into account the potential for reinfection of hogs from wild animals.

Detection of conjugative R plasmids conferring chloramphenicol resistance in Escherichia coli isolated from domestic and feral pigeons and crows.

A total of 87 domestic pigeons of 2 lots and 184 feral pigeons of 15 lots were examined from 1975 to 1977 for the presence of drug-resistant (especially chloramphenicol resistant) Escherichia coli. 20 (23.0%) of the domestic pigeons of the 2 lots, and 39 (21.2%) of the feral pigeons of 5 lots (33,3%) showed resistant E. coli. Usage of selective media containing chloramphenicol, streptomycin or tetracycline resulted in the increase in isolation frequency of resistant E. coli excepting one lot of domestic pigeons in which isolation of chloramphenicol resistant E. coli was very frequent without selection by the drug. Among a total of 106 resistant E. coli isolates from pigeons, 64 (60.4%) were multiply resistant and 58 of the 64 isolates were resistant to chloramphenicol. 58 (90.6%) of the multiply resistant E. coli carried conjugative R plasmids, including 13 thermosensitive R plasmids. 8 (19.0%) of 42 singly resistant E. coli isolates had conjugative R plasmids. 10 crows of 2 lots were examined similarly. Half of them had resistant E. coli. 15 (78.9%) of a total of 19 resistant E. coli isolates were multiply resistant. Of the 15 multiply resistant E. coli isolates, 5, from 2 Japanese jungle crows, were resistant to chloramphenicol. 11 (73.3%) of the 15 multiply resistant isolates carried conjugative R plasmids, including one thermosensitive R plasmid. Difference of drug resistance status between Salmonella and E. coli isolated from pigeons was discussed.

The abdominal air sac ostium of the domestic fowl: a sphincter regulated by neuro-epithelial cells?

A microscopic study of the ostium of the abdominal air sac of the domestic fowl has shown that the ostium has a sphincter-like ring of well innervated smooth muscle. Three types of neuro-epithelial cell characterised by their content of numerous large granular vesicles are found in the wall of the ostium. Type I cells are present within the submucosal nerve plexus and appear to be morphologically similar to SIF cells. Type II cells occur in the lamina propria, in clusters or cords, are often associated with fenestrated capillaries, and have synaptic contact with axonal terminals containing small agranular vesicles. The cells of Types I and II are not intra-epithelial and therefore differ from the cells which have been found elsewhere in the respiratory tract of the domestic fowl and other vertebrates. Type III cells are intra-epithelial, and some of those in the basal region of the epithelium are associated with axon terminals. Type III cells are similar in ultrastructure and location to neuro-epithelial cells found elsewhere in the major airways of the domestic fowl. They also resemble cells in neuro-epithelial bodies in amphibian, reptilian and mammalian lungs, although neuro-epithelial bodies have not been found in the lung of this species of bird. The morphology of the ostium suggests that it may have a sphincter-like function, possibly regulated by the neuro-epithelial cells. The presence of a mucociliary epithelium and defensive tissue in the lamina propria indicates that the ostium is the site of defence mechanisms.
