[Clarification of teat stenoses in cattle by ultrasound].

Ultrasonography and radiography were used as an adjunct to clinical examination in the evaluation of 73 obstructed teats in 63 dairy cows. The images obtained with a 3.5 MHz and a 5 MHz linear array transducer were compared with radiographs and correlated with findings obtained at surgery. Ultrasonography and radiography allowed a correct assessment of the lesions in 68 respectively 58 teats. In five cases the obstructive lesions in the teat canal were not clearly discernible when ultrasonography was used. Radiography was the method of choice for the evaluation of the teat canal and small mucosal folds in the milk cistern. Ultrasonography was the method of choice for the detection of obstructive lesions at the base of the teat; all 14 of these cases were assessed correctly using ultrasonography versus three of 14 when radiography was used. Ultrasonography is a useful tool for the practitioner to evaluate obstructive teat lesions.

Periampullary, colorectal and gastric cancer in two siblings.

We describe a sibship affected by subsequent periampullary, colorectal and gastric carcinoma. Three of 4 siblings (2 males, 1 female) developed a periampullary carcinoma at the age of 20, and the 2 brothers subsequently had colorectal and gastric carcinoma. One of them also had familial adenomatous polyposis. There is suggestive evidence of vertical transmission of a gene predisposing to a hereditary colorectal carcinoma syndrome.

Implications of dose distribution on monitoring requirements in U mines and mills.

In U mines and mills, mean doses from gamma radiation and 222Rn daughters, respectively, range from 10-30% of the individual limits recommended by the International Commission on Radiological Protection (ICRP), while the mean exposure to long-lived dust can be as low as a few percent or as high as 30% of the ICRP recommended limit. In certain mines, 220Rn daughters are present and should also be measured and accounted for. When the doses (or dose equivalents) from all the components of the radiation sources are taken into account, according to the ICRP notions of effective dose equivalent and committed effective dose equivalent, the mean of the combined doses can reach 30-50% of the combined permissible limit of dose. It is generally observed that individual doses and exposure to radiation are log-normally distributed. Since individual exposures to each specific hazard are generally not correlated, there is a probability that a number of individuals belong to the upper part of each exposure distribution. Therefore, it can happen that non-negligible fractions of the populations are liable to be close to the combined dose limit or to be overexposed. Consequently, in view of the observed nature of the distributions and the need to account for all sources of radiation, it is essential that appropriate radiation monitoring techniques be used to measure and record all significant doses and exposures. The analysis of the results of appropriate monitoring practices will lead to improved engineering controls of radiation hazards and optimum use of preventive resources.

Treatment of active rheumatoid arthritis with slow intravenous injections of thymopentin. A double-blind placebo-controlled randomised study.

41 patients with active rheumatoid arthritis entered a placebo-controlled double-blind randomised study in which 21 received slow intravenous injections (given in fractions over 10 min) of thymopentin (TP-5) 50 mg 3 times a week for 3 consecutive weeks and 20 received placebo in the same way. After 3 weeks of treatment the TP-5 group showed improvement (p less than 0.05 or p less than 0.01) in all but one of the clinical variables tested. There was improvement in the number of joints painful at rest, the number of joints painful on motion, scores for tenderness on pressure and swollen joints, severity of pain on awakening and morning stiffness, and right-hand grip strength; left-hand grip strength remained unchanged. In the placebo group, only morning stiffness improved significantly. The intergroup comparisons showed that thymopentin was significantly better than placebo in reducing tenderness, joint swelling, severity of pain on awakening, and disease activity. 4 weeks after the end of the TP-5 therapy, the improvement was still present although there was a trend towards relapses. No significant modifications occurred in any of the laboratory variables tested and only minor side-effects were experienced by either group.

Clinical experience and results of treatment with suprofen in pediatrics. 4th communication: Assessment of pain in babies and infants/Analgesic effect of suprofen syrup in otitis media.

In a study including a total of 175 children, ranging in age from 3 months to 3 years and suffering from otitis media, the analgesic effect of alpha-methyl-4-(2-thienylcarbonyl)-phenyl acetic acid (suprofen, Suprol) syrup was compared with that of lidocaine 0.03 g/6 g + phenazone (phenyl-dimethylpyrazolone) 0.03 g/6 g (L PDP) ear drops. The study was designed as an open controlled trial. The test medications were applied in single doses: suprofen 5-7.5 mg/kg b.w., orally; (L PDP) 1 drop, locally. The severity of pain was assessed in the beginning of the treatment and 2 h following administration of the drugs. The results were indicative of the fact that in children on suprofen syrup marked pain relief was obtained, whereas the painful condition of children on L PDP ear drops even deteriorated.

Safety of thymopentin. Data from European clinical studies.

The safety data collected from 196 patients treated with thymopentin during the clinical development of this compound in Europe are reviewed and compared with the incidence of adverse drug reactions experienced when using a commercial nonsteroid anti-inflammatory drug. Quantitatively side effects are reported in the same range for both drugs, however, they appear to be quite different when classified by body systems. Some patients complained about somnolence, and it is speculated whether this symptom might be related to thymopentin's known effect on the neuromuscular junction. The general conclusion is that thymopentin is an extremely well tolerated drug when used according to the dose regimens recommended.

Clinical experience and results of treatment with suprofen in pediatrics. 1st communication: Suprofen dosage for children/An open and a double-blind study with suprofen syrup.

The antipyretic effect of single doses of alpha-methyl-4-(2-thienylcarbonyl)-phenyl acetic acid (suprofen, Suprol) syrup, administered at dose levels of 1, 2, 3, 4, 5, 7.5, and 10 mg/kg b.w., was tested in a randomized double-blind and a subsequent open study. The test populations consisted of 100 children in the double-blind study and 40 patients in the open test (20 subjects/group). The patients' age ranged from 2 to 12 years; the lowest initial rectal temperature was 39.0 degrees C. The treatment groups were homogeneous as to demographic data. The temperature was reduced in all treatment groups. In the double-blind study the mean value dropped under the subfebrile threshold of 38.0 degrees C only in the group on 5 mg/kg and remained then constant for up to 6 h following administration. No sufficient antipyretic effect was obtained with lower doses. The results of the additional open study with doses of 7.5 and 10 mg/kg indicated good antipyretic effect. This effect was not, however, superior to that obtained with 5 mg/kg. Pulse and respiratory rates returned to normal within 1.5 h following administration, except in patients on 1 mg/kg. A total of 10 patients, homogeneously distributed in the treatment groups, experienced vomiting as an adverse reaction. Short-term hypotonia was seen in one subject on 7.5 mg/kg. The results obtained show that single doses of suprofen upward of 5 mg/kg b.w. exert satisfactory, long-lasting, antipyretic effect on children.

Clinical experience and results of treatment with suprofen in pediatrics. 2nd communication: Use of suprofen suppositories as an antipyretic in children with fever due to acute infections/A single-blind controlled study of suprofen versus paracetamol.

The present randomized single-blind trial was performed to study antipyretic effect and tolerability of alpha-methyl-4-(2-thienylcarbonyl)-phenyl acetic acid (suprofen, Suprol) suppositories versus paracetamol (acetaminophen) suppositories in pediatric patients with fever of various etiology. The study included a population of 120 patients ranging in age from 2 to 12 years; the subjects' mean rectal temperature was 39.3 degrees C in the beginning of the therapy. The dosage of the suppositories depended upon body weight; medication was applied up to 3 times a day. The temperatures were recorded 0.5, 1, 1.5, 2, 3, 4, 5, and 6 h after the preparation was first applied. Pulse rates and respiratory rates were measured at the same rating times. The antipyretic effect of suprofen in younger patients was from 1 through 6 h (except at 3 h) statistically significantly superior to that of paracetamol. In older children, the differences in favor of suprofen were statistically significant only at 1 and 2 h after application of the drug. After the treatment pulse and respiratory rate dropped in both age groups on either treatment. The means were within the normal range at all rating times. The only adverse reaction was vomiting; this phenomenon occurred in 4 cases, i.e., in 2 cases each on either drug.

Clinical experience and results of treatment with suprofen in pediatrics. 3rd communication: Antipyretic effect and tolerability of repeat doses of suprofen and paracetamol syrup in hospitalized children/A single-blind study.

Antipyretic effect and tolerability of alpha-methyl-4-(2-thienylcarbonyl)-phenyl acetic acid (suprofen, Suprol), syrup and paracetamol (acetaminophen) were compared within the scope of the present randomized single-blind study; the test population included a total of 115 children ranging in age from 6 months to 12 years. All patients were admitted to the hospital with an average temperature of 39.3 degrees C, their disease being caused by bacterial or viral infections. The dose levels for treatment with syrup depended upon the children's age and body weight. Treatment was in most cases given for two days; a three-times-a-day schedule was used. The (rectal) temperature as well as pulse and respiratory rates were measured prior to treatment and 0.5, 1, 1.5, 2, 3, 4, 5, 6 h after first administration of the test preparations. The results showed that the antipyretic effect of suprofen was in both age groups at all rating times statistically significantly superior to that of paracetamol. Pulse and respiratory rates dropped in both age groups after treatment; the means were within the normal range at all rating times. Adverse drug reactions were seen in 5 patients on suprofen and in 3 cases on paracetamol. It is, however, questionable whether such reactions are drug-dependent.

Antipyretic effect and tolerability of suprofen suppositories. Controlled clinical double-blind study with placebo.

The aim of the present study was to investigate the antipyretic effect of alpha-methyl-4-(2-thienylcarbonyl)-phenyl acetic acid (suprofen, Suprol) 300 mg suppositories compared to placebo in patients with fever of various etiology. The trial was designed as a randomized double-blind study including 30 patients per treatment group. After insertion of the suppository, temperatures were measured after 30 min, 1, 2, 3, 31/2, 4, 5, and 6 h. The study was performed at four investigational centers. At the end of the study, a total of 61 patients could be evaluated: 27 on suprofen, 34 on placebo. There were no statistically significant differences in the anamnestic data. The mean age of the subjects on suprofen was 66.5 years, and on placebo 61.3 years. Prior to treatment, the mean temperatures in the two treatment groups were 38.8 and 38.9 degrees C, respectively. In the suprofen group, the temperature dropped to a mean of 37.9 degrees C within 3 h and to 37.6 degrees C within 6 h. The decrease in temperature was less marked in the placebo group; here the mean temperature was 38.4 degrees C after 3 h and 38.2 degrees C after 6 h. Suprofen was found to be superior to placebo throughout the study, the differences being statistically significant after 3 h up to 6 h. The only side effect experienced by a subject on suprofen was vomiting.

Double-blind study of suprofen vs naproxen in the treatment of osteoarthritic pain.

In a 2-week double-blind study involving 79 patients with mainly osteoarthritis of the hip and knee, Suprofen and Naproxen were compared for efficacy and tolerability in the treatment of the symptoms of the disease. The drugs were administered on a b.i.d. schedule: 800 mg of Suprofen or 750 mg of Naproxen. Nocturnal pain, pain at rest, pain on motion and tenderness were evaluated at baseline and at days 7 and 14. Results showed that patients in both groups were significantly improved in all parameters. Between the groups no statistically significant differences were found. Thus, Suprofen was as effective in pain relief as Naproxen. One patient in the Suprofen group and two patients in the Naproxen group experienced mild gastrointestinal symptoms. Overall tolerability was very good.

[Treatment of postoperative wound pain with suprofen].

The present randomized double-blind study was performed to investigate the analgesic effects of single doses of suprofen (alpha-methyl-4-(2-thienylcarbonyl)benzene acetic acid; Suprol) 200 mg, suprofen 400 mg paracetamol (APAP, acetaminophen) 650 mg, and combination suprofen 100 mg + APAP 650 mg versus placebo. The five treatment groups were homogeneous as to their demographic features and comprised 28--32 subjects each. Data for a total of 146 patients were evaluated. There were statistically significant differences between the therapeutic effect of the test preparations containing active substance on the one hand and placebo and the other hand. Of the active substances, the best results were obtained with the combination suprofen 100 mg + APAP 650 mg, followed by suprofen 400 mg and APAP 650 mg; there were hardly any differences in the results obtained with the two latter substances. Suprofen 200 mg ranked third. Statistical significance was only seen for the parameter pain intensity (SPID) on comparison of suprofen 100 mg + APAP 650 mg versus suprofen 200 mg. Side effects, homogeneously distributed over the treatment groups, were observed in four cases.

[Total synthesis of somatostatin-28 (author's transl)].

The total synthesis of the octacosapeptide corresponding to the proposed primary structure of porcine somatostatin-28 is described. The synthesis has been performed using a protection scheme of maximum selectivity (acid labile side chain protection based on tert-butyl alcohol and 1-adamantol derived protecting groups in combination with the S-tert-butylthio group for reversible and selective blocking of the cysteine thiol functions and the 2-nitrophenylthio group for the temporary protection of the alpha-amino functions of intermediate segments) and of carefully selected fragments. Upon assembly in sequence order of the four suitably protected fragments related to sequences 18-28, 15-17, 8-14 and 1-7, the asymmetric disulfides were reduced by exposure of the fully protected octacosapeptide to phosphines. Subsequently, the final deprotection was performed with trifluoroacetic acid and the resulting dihydrosomatostatin-28 was then converted by air oxidation into the "cyclic peptide". Gel filtration on Biogel P-6 and ion-exchange chromatography on Biogel CM-2 produced somatostatin-28 at a high degree of purity. Comparative analysis of the synthetic and natural product by means of chromatographic, immunological and biological assays confirmed the structure proposed for this putative precursor of somatostatin-14.
