A preliminary study on the anthelmintic activity of Calotropis procera latex against Haemonchus contortus infection in Najdi sheep.

The anthelmintic activity of Calotropis procera latex was investigated in sheep that had been infected with single oral doses of 12000 infective Haemonchus contortus larvae. Inappetence, dullness, erosive abomasitis, decreased haemoglobin concentration and increased eosinophils were the main features of haemonchosis in the sheep. In the sheep treated with single oral doses of 0.01 ml or 0.02 ml/kg body weight of C. procera latex, egg production was significantly reduced, but not completely suppressed, and fewer adult Haemonchus worms were found in the abomasum. Although the appetite improved, the haemoglobin concentration and serum copper, iron and zinc levels were still reduced after therapy with Calotropis latex. Calotropis latex showed a concentration-dependent larvicidal activity in vitro within 20 min of application.

Combined toxicity of Cassia senna and Citrullus colocynthis in rats.

Body weight loss, inefficiency of feed utilization, diarrhea, ruffled hair and enterohepatonephrotoxicity were effects on male Wistar rats fed diet containing 10% Cassia senna or 10% Citrullus colocynthis ripe fruits for 6w. Rats fed a 1:1 mixture (5% + 5%) of fruits from these plants were more adversely affected and had deaths than rats fed the individual plants. The changes associated with the macrocytic hypochromic anemia and leukopenia were increased serum AST, ALT and ALP activities, increased urea, and decreased total protein, albumin and calcium. Serum bilirubin concentration did not change.

Preliminary toxicity study on the individual and combined effects of Citrullus colocynthis and Nerium oleander in rats.

The toxicity of diet containing 10% of Citrullus colocynthis fruits or 10% of Nerium oleander leaves or their 1:1 mixture (5%+5%) for rats treated for 6 weeks was determined. Dullness, ruffled hair, decreased body weight gains and feed efficiency, and enterohepatonephropathy characterised treatment with C. colocynthis and N. oleander given alone. Diarrhoea was a prominent sign of C. colocynthis poisoning. Organ lesions were accompanied by leucopenia, anaemia and alterations in serum AST, ALT and ALP activities and concentrations of total protein, albumin, urea, bilirubin and other serum constituents. Feeding the mixture of C. colocynthis and N. oleander caused more marked effects and death of rats.

Effects of pearl millet (Pennisetum typhoides), and fermented and processed fermented millet on Nubian goats.

The effects of Pearl millet, fermented millet, or processed fermented millet were investigated in 15 goats assigned as untreated controls, Pearl millet-fed (166.6g/animal/d), fermented millet-fed (166.6 g/animal/d or 83.3g/animal/d), and processed fermented millet-fed (166.6g/ animal/d). Pearl millet caused goiter within 72-108 d, and changes in thyroid follicles were correlated with clinical manifestations and alterations in serum and tissue iodine and selenium concentrations. Neither fermented nor processed fermented millet produced goiter, but their toxicity was characterized by ruminal bloat, dyspnea, diarrhea, ataxia, and enterohepatonephrotoxicity with death within 5-15 d. Organ lesions correlated with changes in serum enzymes and other serum constituents, hematology, and tissue and serum iodine and selenium concentrations.

Toxicity of Chrozophora obliqua in rats.

The toxicity to Wistar rats of Saudi Chrozophora obliqua used in traditional medicine for the treatment of diverse ailments was investigated. C. obliqua leaves were fed to rats at 2% or 10% of the standard diet. When compared with controls, body weight gains and feed efficiency were adversely affected by both treatments. Although the rats fed 10% C. obliqua diet had the lowest growth rate, bouts of soft faeces and enterohepatonephropathy no death occurred among the rats. These changes were accompanied by increases in serum GGT and AST activities, in urea and cholesterol concentrations, decreases in total protein and albumin levels, macrocytic hypochromic anaemia and leucopenia.

Comparative effects of diazinon and malathion in Najdi sheep.

The comparative effects of diazinon and malathion on Najdi sheep were described in sheep allotted as untreated controls, diazinon-treated at 25 mg/kg/d or 50 mg/kg/d, and malathion-treated at 25 mg/kg/d or 50 mg/kg/d. Although serum cholinesterase (ChE) activity was reduced, neither significant clinical signs nor severe pathological changes were produced in sheep dosed orally with 25 or 50 mg diazinon/kg/d for 21 d. Both oral dose levels of malathion were lethal to sheep between 1 and 6 d and caused, prior to death, hyperexcitability, tremors, clonic convulsions, salivation, nasal discharge, incoordination of movement, paresis of the limbs and recumbency. Lesions were widespread congestion and hemorrhage, patchy pulmonary cyanosis, gastroenteritis and hepatonephropathy. These changes were accompanied by increases in the activities of serum SDH and AST, in the concentrations of urea, triglyceride and cholesterol, and decreases in ChE activity and in RBC, PCV and Hb values.

Toxicity of Commiphora myrrha to goats.

An investigation was made of Commiphora myrrha used in traditional medicine for the treatment of various ailments. Twelve 6-mo-old male Nubian goat kids were assigned to 4 groups: undosed controls, C myrrha-dosed at 0.25 g plant resin/kg/d, C myrrha-dosed at 1 g resin/kg/d and C myrrha dosed at 5 g plant resin/kg/d. Results of hepatorenal function tests were correlated with clinical and pathological changes. The use of 1 or 5 g plant resin/kg/d caused grinding of teeth, salivation, soft feces, inappetence, jaundice, dyspnea, ataxia and recumbency. Death occurred between 5 and 16 d. Enterohepatonephrotoxicity was accompanied by anemia, leucopenia, increases in serum ALP activity and concentrations of bilirubin, cholesterol, triglycerides and creatinine, and decreases in total protein and albumin. The oral dose of 0.25 g plant resin/kg/d was not toxic.

Effects of amitraz given by different routes on rats.

Three-mo-old male Wistar rats were sprayed with 250, 500, 1000 and 2000 ppm amitraz 2 w apart or given single doses of 50, 100, or 250 mg/kg p.o, i.m. or i.p. No effects were observed in the amitraz-sprayed rats. Single doses of amitraz p.o, i.m. or i.p. was non-toxic at 50 mg/kg, toxic at 100 mg/kg and lethal at 250 mg/kg within 24 h of dosing. Survivors were killed 48 h post-dosing. Features of toxicity were depression, incoordination of movement, paresis of the limbs, hepatonephrotoxicity, muscular hemorrhage at site of injection and peritonitis following i.p. injection. These changes, accompanied by leucopenia, were correlated with alterations in serum AST and concentrations of serum constituents. Amitraz did not inhibit serum ChE activity.

Experimental Rhazya stricta toxicosis in rats.

Saudi Rhazya stricta is used in folkloric medicine for the treatment of various disorders. R stricta leaves were fed to male Wistar albino rats at 2%, 10% or 50% of the diet for 6 w. Decreased growth rate, soft feces, dullness, ruffled hair and hepatonephrotoxicity were observed in rats on 10% and 50% Rhazya diet. Fifty percent Rhazya was fatal to rats, and hepatorenal lesions at 3 and 6 w confirmed changes in serum enzyme activity and in total protein, albumin, bilirubin and urea concentrations. Serum copper was decreased and zinc was increased in rats on 50% R stricta at 3 and 6 w, and were accompanied by anemia and neutropenia. Two percent Rhazya diet promoted growth as the plant leaves contained 28.3% crude protein and 16.6% crude fat and were not deficient in copper, zinc or iron.

Studies on laticiferous plants: toxic effects in goats of Calotropis procera latex given by different routes of administration.

The effects on goats of Calotropis procera latex given by different routes of administration were investigated. The administration of latex at 1 ml/Kg body weight via the oral route or at 0.005 ml/Kg body weight/day via the intravenous or intraperitoneal route caused death of the goats between 20 minutes and 4 days. When the small dose of latex (0.005 ml/Kg body weight/day) was given by the oral route or intramuscular route no death among the goats occurred. Nervous signs, frequent urination, frothing at the mouth, dyspnoea and diarrhoea were the main features in goats given latex by the oral, intravenous or intraperitoneal route. Lameness was observed in goats given latex via the intramuscular route. Lesions were widespread congestion and haemorrhage, pulmonary cyanosis, enterohepatonephropathy, peritonitis (in goats receiving latex via i.p. route) and haemorrhagic myositis at the site of latex injection. These changes were accompanied by increases in the activities of serum GDH, LDH, ALP, GGT and AST and in the concentrations of cholesterol, urea and creatinine and decreases in the level of total protein.
