Blood Pressure Lowering And Vasomodulator Effects Of Piperine, Syed Intasar Husain Taqvi, Abdul Jabbar Shah, Anwar Gilani

Department of Biological & Biomedical Sciences

This study was aimed to explore underlying mechanism(s) of cardiovascular effects of piperine. Intravenous administration of piperine caused a dose-dependent (1 to 10 mg/kg) decrease in mean arterial pressure (MAP) in normotensive anesthetized rats, the next higher dose (30 mg/kg) did not cause any further change in MAP. The fall in blood pressure (BP) was followed by small increase in MAP after each dose. In Langendorrf's rabbit heart preparation, piperine caused partial inhibition and verapamil caused complete inhibition of force and rate of ventricular contractions and coronary flow. In rabbit aortic rings, piperine inhibited high K(+) (80 mM) precontractions and …

Rhabdomyosarcoma Embryonal Type: In A Three And A Half Year Old Girl, Ameer A Khowaja, Saqib Ali Gowani, Asmatullah Khan, Saulat H. Fatimi

Department of Biological & Biomedical Sciences

Rhadomyosarcoma is the most common tumour of the soft tissues in infants and children. We report a case of a 3 1/2 year old girl who presented with a swelling over the neck. Swelling was diagnosed as Rhabdomyosarcoma (embryonal type). Tumour mass was found to be unresectable initially. The patient was subjected to multiple courses of checmotherapy, which shrunk the tumour significantly. There was simultaneous development of cystic lesions in upper lobe of right lung. Excision of the remnant rhabdomyosarcoma mass and biopsy of right lung with cystectomy of right upper lobe cystic lesion was performed. The patient fully recovered …

Migraine And Patent Foramen Ovale: Exploring The Association And A Possible Treatment Option, Muhammed Yaser Hasan

Department of Biological & Biomedical Sciences

Migraine is a very common type of headache. With a prevalence of 10-12%, migraine ranks 19th among diseases causing worldwide morbidity. Number of studies have shown a high prevalence of patent foramen ovale (PFO) in patients with migraine, especially migraine with aura. The right to left shunting of blood in a PFO could serve as a conduit for chemicals that would exert a trigger effect on hyper excitable neurons leading to the development of migraine. Furthermore patients with PFO and migraine also show a marked improvement in their symptoms after percutaneous closure of the PFO. This review is a close …

N-Acetyl-B-D-Glucosaminidase And Inflammatory Response After Cardiopulmonary Bypass, Perwaiz Iqbal, Hasanat M Sharif, Naseema Mehboobali, Farzana A Yousuf, Abrar H Khan, Frank W Sellke

Department of Biological & Biomedical Sciences

OBJECTIVE: To determine the changes in activity of plasma N-acetyl-beta-D-glucosaminidase, a marker for inflammation as well as renal, pulmonary and cardiac damage and proinflammatory cytokines in patients undergoing coronary artery bypass grafting and find out the relationship between their plasma levels with clinical outcome of patients.

STUDY DESIGN: Cross-sectional study.

PLACE AND DURATION OF STUDY: The Aga Khan University, Karachi, from January to June 2003.

PATIENTS AND METHODS: N-acetyl-beta-D-glucosaminidase (NAG) activity and concentrations of tumor necrosis factor-alpha of (TNFalpha), interleukin 6 (IL-6), interleukin 8 (IL8) and granulocyte-macrophage colony stimulating factor (GM-CSF) were monitored in plasma samples of 12 angina patients …
