RESUMO

INTRODUCTION: Cigarette smoking is worldwide problem which can be correlated with teratogenicity. Tocopheryl acetate plays as an antioxidant against the oxidative stress evolved by cigarette smoke exposure during pregnancy. AIM: To study the effect of maternal exposure to cigarette smoke and Tocopheryl acetate on fetuses of mice. MATERIALS AND METHODS: Pregnant mice randomly assigned to different groups (Group I (control), Group II (Tocopheryl acetate), Group III(soyabean oil used as vehicle for Tocopheryl acetate), Group IV (Cigarette smoke Exposed), Group V (Cigarette smoke exposed plus Tocopheryl acetate) and Group VI(Cigarette smoke exposed plus soyabean oil) were exposed to cigarette smoke 3 times a day for 20 minutes each time and Tocopheryl acetate with dose of 200mg/kg/day in 0.3ml of soyabean oil as vehicle orally through oral gavage from the 5th day of gestation to 15th day. RESULTS: Cigarette smoke exposed mice showed significant fetal weight loss, resorption, placental anomalies, severe growth retardation, venous congestion, haemorrhage, limbs defects and enphalocele. Negligible abnormalities were seen among the control and Tocopheryl acetate group. Cigarette smoke exposed group with Tocopheryl acetate exhibited weight gain among the fetus as well as no gross abnormalities. The oxidative stress was significantly increased by increasing Malondialdehyde (MDA) 293±81.57 µmol/mg (p<0.0001) and decreasing Superoxide Dismutase (SOD) 1.43 ± 0.23mg/ml, (p<0.0001) Reduced Glutathione (GR) 0.017±0.002mg/ml, (p<0.01) and Catalase (CAT) 0.248±0.005mg/ml, (p<0.0001). Tocopheryl acetate induced group significantly maintained the oxidative stress with all p <0.0001. CONCLUSION: It can be concluded that Tocopheryl acetate may have an ameliorating effect on the cigarette smoke during pregnancy on fetus.

RESUMO

During routine dissection of a 42 year old male Indian cadaver posterior abdominal wall, variations in the testicular vessels were observed. The right testicular artery arose from the right accessory renal artery, which originated from the ventral aspect of the abdominal aorta. The left testicular artery originated from the ventral aspect of the aorta in almost the same horizontal line as the right accessory renal artery, just below the superior mesenteric artery and 1.79 cm, above the origin of the renal arteries. The right vein drained into the right accessory renal vein instead of the inferior vena cava, while the left testicular vein drained into the left renal vein. The presence of variation of both the testicular arteries as well as the testicular vein is seldom seen together.


Durante una disección de rutina de un cadáver, perteneciente a un hombre indio de 42 años, se observaron variaciones en los vasos testiculares en la pared abdominal posterior. La arteria testicular derecha se originó desde la arteria renal accesoria, proveniente de la cara ventral de la parte abdominal de la aorta. La arteria testicular izquierda se originó en la cara ventral de la parte abdominal de la aorta, casi en la misma línea horizontal de la arteria renal accesoria derecha, justo distal a la arteria mesentérica superior y 1,79 cm sobre el origen de las arterias renales. La vena renal derecha drenaba en la vena renal accesoria en lugar de la vena cava inferior, mientras que la vena testicular izquierda drenaba en la vena renal izquierda. En muy pocas ocasiones es posible observar de manera conjunta, variaciones tanto de las arterias como de las venas testiculares.
