Forty-two albino male adult rats with atherosclerosis induced by 0.5% hydrogen peroxide, 4.69% saturated animal fats and 0.26% cholesterol added to the diet, were used in this study as experimental and biological model. Their body weights ranged between 250-275g and aged 3-4 months. They were divided into seven equal number and identical body weights groups. The first group was a negative control, second group was a positive control (standard group), orally treated with 0.57% Flavostatin /Kg body weight, third and forth groups were orally treated with 300 and 600mg peanut oil extracts/Kg body weight respectively, fifth and sixth groups were orally treated with 120 and 240mg peanut aqueous extracts/Kg body weight respectively, seventh group fed the atherogenic diet containing 10% peanut cake. All groups were fed atherogenic diet (containing animal fats and cholesterol) and treated with 0.5%H2O2 in freshly prepared drinking water daily ad libitum. The experimental period was continued for 15days, in addition to 30days during which the rats were prepared for induction of atherosclerosis by 0.5% H2O2 with drinking water and atherogenic diet. Analysis of variance and Duncan multiple tests showed that, the peanut aqueous extract/Kg rat body weight and 10% peanut cake exerted a significant (p<0.05) decreasing effect on serum total lipids (TL), cholesterol (TC), triglycerides (TG), phospholipids (PL) and the undesirable very low density (VLDL-c) and low density (LDL-c) lipoproteins, atherogenic indices and malondialdehyde content of liver, heart and kidney. On the other hand, they caused increased levels of the desirable high density lipoprotein, while the peanut oil extract caused undesirable increase in serum VLDL-c and LDL-c lipoproteins, TC and TG.

In this study, various types of fetal malformations, including cleft palate were induced by the intraperitoneal administration of cyclophosphamide to pregnant mice. The dose 75 mg/kg b.w. when given at the 12th day of gestation has lead to multiple defects including cleft palate, flat head, curved head, exencephaly, shortening of the extermities, and smaller size of the fetus. When the same dose was given at the 13th day of gestation, the malformations included curved head, exencephaly, shortening of the extermities and a lower percentage of cleft palate. When given at the 14th, 15th, or 16th days of gestation, it lead to curving of the head and small size of the fetus. Cleft palate was confirmed histologically as the palatine shelves were quite apart. Additionally, there were thickening and vacuolar degeneration of the epithelial element of the shelves. The core of the shelve consisted of pleomorphic mesenchymal cells with foci of chondroblastic proliferation.

The study included initiation and growth of callus from stem Nigella sativa L. using Murashige and Skoog (MS) medium containing 106- 1010 molar 2,4 -dichlorophenoxy acetic acid (2,4-D) or pentadienoic acid (PDA). Glutamate dehydrogenase (GDH) was partially isolated from the initiated callus on the nutrient medium containing variable concentrations of potassium and ammonium nitrates. In addition, a comparative study of the enzyme activity was performed in the presence of 2,4-D or PDA.
The results revealed that best medium for initiation and growth of callus was obtained in the presence of 106- M of 2,4-D or PDA. The fresh weight of the callus grown on MS medium in the presence of 2,4-D or PDA was 5.72 gm and 2.81 gm respectively after 45 days of culturing. However, the protein content of the callus was 1.050 and 1.116 mg / gm fresh weight grown on media containing 2,4 –D or PDA, respectively.
The results also predicted that the specific activity of GDH was increased by 23 folds after partial purification. The optimum conditions for GDH activity were obtained using: 100 mmole of Tris – HCl buffer, at 35º, pH of 8.6, 1 µmole of NAD, 20 µg of protein as a source for the enzyme and 30 µmole of glutamate as a substrate. Using Linweaver – Burk plot, the value of Michaelis – Menten constant (km) was 27 µmole. The results also revealed that the specific activity of GDH isolated from the callus where 2,4–D or PDA was added is 21.3 and 22.3 µmole / min / mg protein, respectively using the optimum conditions.
The comparative molecular weight of GDH was determined using gel filtration chromatography and found to be in the range of 302000 dalton.
Based on the results from the current study it was concluded that PDA could be used instead of 2,4-D in plant tissue culture of Nigella sativa L. Its action is similar somehow to the standard auxin. Therefore, PDA could be considered as a synthetic auxin and used in plant tissue culture for several plants.

Pregnant albino rats were treated with oxfendazole at doses(7, 5, 15, 30, and 60 mg/kg, orally) during organogenesis (on day 6-15 of pregnancy) which produced dose- dependent embryotoxicity. The doses of (30 and 60 mg/kg)caused a high percentage of resorption of embryos (83,33% and 100%), respectively, as well as the dose of (30) mg/kg a significant decreased in the numbers, weights and lenghs of fetuses, and placental weights and diameters. Whereas the dose of (7,5) mg/kg did , not produced embryotoxic effects. The effects of oxfendazole on pregnant rats of a dose (60) mg/kg (orally) on differents stages of gestation: preimplantation, organogenesis and histogenesis and function maturation were depend on the stage of embryonic development. The effects were high on the stage of organogenesis where oxfendazole caused full resorption of embryos. While the effect of oxfendazole on 3 rd stage of gestation manifested by significant decreased in the weights and lengths of fetuses. Pregnant rats were treated with oxfendazole at doses(15 and 30) mg/kg (orally) during organogenesis significantly increased the percentage of neonatal mortality on postnatal day (PND1) (36%, 95%) respectively, these effects were dose dependent, as well as oxfendazole at dose (30) mg/kg caused significant decreased in the litter size, the body weight of the progeny (PND1), as sharply reduced the percentage of survival of the pups to weaning to (0%) on the (PND2). The doses at (15and 30) mg/kg were teratogenic causing extermal anomalies (tail deformity) were found in 1 offspring of each group.
