[Appointment of correlation between stroke and serum level of homocysteine, folic acid and vitamin B[12]]

A stroke, or cerebrovascular accident [CVA], occurs when blood supply to part of the brain is disrupted, causing brain cells to die. Often by a blood clot or a fatty deposit due to atherosclerosis. CVA is third cause of death in the world and the most common causes of neurologic dysfunctions. There are different risk factors associated with CVA including systolic or diastolic hypertension, hyperlipidemia, smoking, alcohol abuse. Moderately increased concentration of homocysteine without homocystuinoria associated with increase of atherosclerosis, CVA and over ally mortality. The most common form of hyperhomocysteinemia is genetic. Increased serum level of homocysteine may reflect deficiency of folate, vitB[6] and vitB[12]. To determine the relationship between serum level of homocysteine, folic acid and vitB[12] and CVA this study was done at a case control survey in 2008 in 40 known case of CVA and 40 control cases are selected among the out patient of neurology clinics of neurologist in Kashan city. Demographic data and other inhumation [age, sex,.] match at case and control group. 2cc venous blood of each patient tested for serum level of homocysteine folic acid and vitB[12] [with HPLC] and of all cases and control classified and analyzed. Among 40 CVA cases 52/5 female [21 cases] 47/5 male [19 cases] and in control group 50 female [20 cases] and 50 male [20 cases]. The mean of the ages at cases attached was 67/15 and in control group was 63/5 and all of the cases and controls was 65/32 and there was not meaningful difference between two groups. In this study the mean of serum level of homocysteine at case attached was 15/56 +/- 4/69 micro mol/l and in control group was 10/15 +/- 4/7 micro mol/l And there was meaningful difference between two groups [P<0/05]. The mean of serum level of folic acid was 8/405 +/- 5/33 ng/ml in case groups was and in control groups 10/87 +/- 8/02ng/ml there was meaning full difference between two groups [P<0.005]. The mean of serum level of vitB[12] in cases attached was 389.02 +/- 208.02 pg/ml and in control groups was 522.82 +/- 218.3 pg/ml and there was meaning full difference between two groups [P<0.05]. This study showed correlation between CVA and serum level of homocysteine, folic acid and vitamin B[12]. It is recommended to conduct prospective studies to evaluate the cause and effect between these supplements and stroke and practical ways of prevention of CVA

[Study of the effect of hemiscorpius lepturus venom on levels of WBC, RBC and hematocrit in rats]

Hemiscorpius lepturus scorpion present in the southern provinces of the country, especially inKhoozestan stings a lot of people that results in long-standing dangerous side effects and sometimes evenmortality. As the study of the effects of this scorpion venom on some laboratory animals can determine itsmechanism of action and help us to cure people stung by scorpions, this study has been done to study the effectsof Hemiscorpius lepturus venom on levels of WBC, RBC and hematocrit of rats.An experimental study has been done on 51 rats of the same race with approximate age of 2-3 months,and weight of 200-250 grams. . All the hematological features including WBC [White Blood Cell], RBC [RedBlood Cell] and HT [Hematocrit] were measured prior to venom injection. The same procedures were followedafter injection of 1 microlitre of venom. Results before and after injection have been analyzed by WilcoxonMatched, Pairs signed and Ranks statistical tests.The results of the study have shown that the venom caused changes in the levels of WBC, RBC andHematocrit. The mean level of WBC at the start was 10234, whereas following the venom injection it reached tothe level of 11757 [P < 0.0007]. The mean number for RBC before the treatment was 7509130 and after injection,the number declined to 7065098 [P < 0.0001]. The average amount of Hematocrit before and after injection was40.087% and 39.0588%, respectively [P < 0.001].Hemiscorpius lepturus venom has some effects on the levels of WBC, RBC and hematocrit of rats.The study of the hematological changes in humans can lead to better study of the effect of this venom andconsequently suitable cure for the injured
