About veterinary education in Iraq.

The cons and pros of veterinary education in Iraq are described. Started as a small institution, with few students and with foreign staffs, then expanded to enroll more than hundred students each year, with all Iraqi staff. The graduates of the Veterinary College played an important role in monitoring animal health, supervising research projects involving animal welfare, some served as educators of various veterinary science specializations, others worked as private practitioners or recruited in the army. Veterinary education was very vital, as other sciences for progress of the country.

Pregnancy in a cow with uterus didelphys.

Uterus didelphys is a congenital defect of monotocous species. This short contribution describes the condition in a cow that had a pregnancy in the right horn and a corpus luteum on the ipsilateral ovary. This finding demonstrates that pregnancy can occur in a cow with uterus didelphys, although the fate of the pregnancy was obviously not known. The case was identified during routine collection of reproductive tracts in a New Zealand abattoir. It is believed to be the first report of uterus didelphys in a bovine abattoir specimen.

Foetal anasarca in Awassi sheep.

Two anasarcous foetuses of Awassi sheep are described. The foetuses were removed from the dams by caesarean section because of dystocia due to failure of cervical dilation. Uterine incision was made in situ because uteri were so distended they could not be brought out from the site of incision. Large quantities of uterine fluids and abnormal thick placentas were found. One foetus weighed about 7 kg and the other 13 kg. The foetal heads were deformed: the upper jaw was prognathic and the left ear of the small foetus was cystic. Necropsy revealed subcutaneous musculature was soft and flabby and abdominal and thoracic cavities contained serosanguinous fluid. Histopathological examination revealed that only the larger foetus had focal aggregates of basophilic nucleated red blood cells and scattered megakaryocytes in the liver. We conclude that anasarca can occur in Awassi sheep, with and without associated extramedullary haematopoiesis.

Effect of triiodothyronine on cyclic AMP and pulmonary function tests in bronchial asthma.

This study was undertaken to evaluate the effect of triiodothyronine, determined by pulmonary function tests and c-AMP plasma and sputum levels, in asthmatic children. Twenty-three children clinically euthyroid and complaining of chronic bronchial asthma were given a triiodothyronine (T3) supply for a period of 30 days. Pulmonary function tests, plasma and sputum cyclic AMP and plasma T3 levels were performed prior to and after T3 therapy. Patients were requested to continue on their usual antiasthma medicines and to try reduction of the doses of the drugs they needed as possible. All patients tolerated well the T3 regimen without any adverse effect. They all reported at the end of the 30 days an obvious subjective improvement of their asthmatic conditions with a decrease in the number of exacerbations. Seven patients stopped their usual antiasthmatic medicines, being maintained on T3 only and 3 have decreased the amount of bronchodilators needed. A significant improvement of pulmonary function tests was noted in all patients. Also, significantly increased levels of plasma and sputum c-AMP were observed after T3 administration in comparison to the control and pretest values. No statistical differences were found in plasma T3 between the control and the patients either before or after T3 therapy. The study revealed that T3 administration to clinically euthyroid chronic asthmatic children induced a beneficial effect. This might be through improvement of c-AMP synthesis. T3 in the doses used is devoid of side effects, proves to be a useful adjuvant to classic antiasthma therapy, and may reduce the amount of bronchodilators needed.

Contraceptive steroid concentrations in women with early active schistosomiasis: lack of effect of antischistosomal drugs.

Plasma concentrations of the oral contraceptive steroids (OCS) ethinyloestradiol (EE2) and levonorgestrel (LNG) have been determined in women with early active schistosomiasis and compared to those obtained in healthy volunteers. Steroid concentrations following a single dose of Ovral (500 micrograms LNG, 50 micrograms EE2) or during a multiple dose regimen were unaffected by the disease. There was no significant effect of the antischistosomal drugs praziquantel (40 mg X kg-1) or metrifonate (10 mg X kg-1 X 3 at 2-week intervals) on plasma steroid concentrations. In regular users of OCS, significantly higher concentrations of LNG were observed than in women who received only a single dose. We conclude that there is no pharmacokinetic reason for withholding OCS from patients with early active schistosomiasis who are also receiving either praziquantel or metrifonate.

Pharmacokinetics of oral contraceptive steroids in Egyptian women: studies with Ovral, Nordette and Norminest.

Plasma concentration profiles and pharmacokinetic parameters have been obtained following single dose administration of three commonly used oral contraceptive steroid preparations, Ovral, Nordette and Norminest to Egyptian women. The constituents of the preparations are as follows: Ovral (50 micrograms ethinyloestradiol, EE2 and 500 micrograms levonorgestrel, LNG); Nordette (30 micrograms EE2 and 150 micrograms LNG); and Norminest (35 micrograms EE2 and 500 micrograms norethisterone, NOR). Peak plasma concentrations of EE2 ranged between 116-160 pg ml-1 for Ovral, 55-78 pg ml-1 for Norminest and 30-70 pg ml-1 for Nordette. There was no significant difference in half-life (t1/2), oral clearance (CL) or apparent volume of distribution (Vd). The relative values of the area under the plasma concentration-time curve (AUC) reflected well the different amounts of oestrogen in each preparation. There was no significant difference in t1/2, CL or Vd for LNG in the 2 preparations containing this progestogen. The mean AUC following Nordette (150 micrograms LNG) was 40% of that following Ovral (500 micrograms LNG; p less than 0.001). Comparing pharmacokinetic parameters for the same dose of LNG (Ovral) and NOR (Norminest) showed the AUC to be decreased and CL and Vd increased in the latter group. The study indicates that the kinetic profile of the OCS in healthy Egyptian women are similar to other ethnic populations.

Mucometra with persistent corpus luteum in goats.

Ovaries of two goats with persistent corpus luteum were studied by histochemical methods. Lutein cells showed moderate alkaline phosphatase and acid phosphatase activity associated with strong delta 5-3beta-hydroxysteroid dehydrogenase and succinic tetrazolium reductase activity. The results are interpreted as an indication that the corpus luteum was functioning.
