Objective(s): The aim of the study was to evaluate the efficacy of ilioinguinal and iliohypogastric nerve block with anatomical landmark and direct visualization technique on postoperative pain relief and use of opioids after lower segment caesarean section.Materials and Methods: In a double blinded randomized clinical trial that conducted in Shahid Akbarabadi hospital of Tehran, 150 pregnant women candidate for elective cesarean section included in the study and randomly allocated into two groups (nerve block with bupivacaine0.25% and control). Procedure of cesarean section was equal in all cases and patients were assigned randomly to receive nerve block with either 20ml of 0.25% bupivacaine (group A-case group) or 20ml of normal saline solution (group B - placebo group) 2 hours after operation. Opioids dose was measured during the postoperative period during 8 hours. Postoperative pain was assessed at 2, 4, 6, 8 hours postoperatively with a visual analog scale (VAS). Data analyzed by SPSS.Results: There was a significant decrease in opioid administration and pain on visual analog scale in group A (nerve block), as compared with Group (placebo). 8 hours after the operation, pain severity in both case and control groups were similar. Total dose of opioid administration was significantly lower in group A (p=0.00).Conclusion: This study shows that ilioinguinal and iliohypogastric nerve block with anatomical landmark and direct visualization technique is good substitution for opioid in postoperative pain control in cesarean sectionBangladesh J Obstet Gynaecol, 2014; Vol. 29(2) : 83-86

And Control

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.

And Control

The majority of blood vessels in the superior cervical ganglion possess a continuous endothelium with tight junctions. These same features have been associated with the blood brain barrier of the central nervous system and peripheral nerves. These vessels may perform a barrier function between the capillary circulation and the superior cervical ganglion. The permeability of the blood vessels in the superior cervical ganglion of the rat was tested by intravenous injection of horseradish peroxidase (HRP). Three experimental groups of four animals each were given intravenous HRP (Sigma Type II) in a dosage of.08 to.15 mg/gm body weight in.5 ml of.85% saline. The animals were sacrificed at five, ten or 15 minutes following administration of the tracer. Superior cervical ganglia were quickly removed and fixed by immersion in 2.5% glutaraldehyde in Sorenson's.1M phosphate buffer, pH 7.4. Three control animals received,5ml of saline without HRP. These were sacrificed on the same time schedule. Tissues from experimental and control animals were reacted for peroxidase activity and then processed for routine transmission electron microscopy.

And Control

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.
