Diagnosis of Sanfilippo Disease Correlating Clinical, Radiological and Biochemical Findings–A Case Report     

Udit Agrawal  Ajay Meshram  Jayant Vagha  Kirti Swarnkar  Kamlesh Palandurkar 《Indian journal of clinical biochemistry : IJCB》2012,27(4):417-421

Mucopolysaccharidoses (MPS) are a group of genetic diseases and its diagnosis is a challenging task due to multiple differential diagnosis. We had combined clinical findings, radiological and ophthalmological features. Biochemical test for urine glycosaminoglycans (GAG) was done for confirmation of diagnosis in the patient. The case of Sanfilippo disease was characterized by slowly progressive, severe CNS involvement with mild somatic disease. Radiological features were suggestive of Sanfilippo disease and urine GAG test for MPS was positive in the case. With the clinical features we had multiple differential diagnoses. The radiological investigations minimized the list and the biochemical test confirmed GAG in urine. In this case the combination of clinical, radiological and biochemical findings confirmed the diagnosis of Sanfilippo disease.  相似文献

江苏种群橄榄蚶同工酶的生化遗传分析     

贾守菊  张永普  叶魏媚  孙雯雯 《温州大学学报(社会科学版)》2009,(6):14-20

采用聚丙烯酰胺凝胶不连续垂直平板电泳技术对江苏种群橄榄蚶不同个体的苹果酸脱氢酶、苹果酸酶、醇脱氢酶、乳酸脱氢酶、淀粉酶、酯酶、超氧化物歧化酶和细胞色素氧化酶8种同工酶进行分析,得到基本图谱,并对其进行了生化遗传分析．共记录了21个基因座位、38个等位基因,其中有11个基因座位（Me-1、Adh-2、Adh-3、Ldh-1、Ldh-2、Amy-1、Amy-2、Est-2、Sod-2、Cod-1和Cod-2）为多态,多态座位比例（P）为0．5238,该比例接近一般海产无脊椎动物的多态座位比例,表明江苏种群橄榄蚶具有一定的遗传变异能力．  相似文献

Biochemical diagnosis of alcoholism     

Subir Kumar Das  D. M. Vasudevan 《Indian journal of clinical biochemistry : IJCB》2005,20(1):35-42

Medically diagnosed alcoholics can be differentiated reliably from non-alcoholics using clinically laboratory tests. In the present study, patients with liver diseases either due to alcohol or without alcohol compared with a group of normal healthy persons. Heavy drinkers showed significantly lower body weight and percent body fat, and low BMI compared with other groups. The percentage of hemoglobin and total number of RBC were found to be significantly decreased, whereas mean corpuscular volume (MCV) significantly increased in alcoholic liver disease (ALD). Hyperbilirubinemia, hyperuricemia and hypoalbuminemia correlate with alcohol intake. Albumin/globulin ratio significantly decreased in ALD. In acute liver injury AST/ALT ratio is ≤1.0, whereas in alcoholic hepatitis it is always >1.0. Moderately elevated level of ALP and high GGT values are good discriminator of alcoholic patients. Alcohol-induced liver injury is linked to oxidative stress as observed by decreased level of reduced glutathione and ascorbic acid, and increased level of thiobarbituric acid reactive substances.  相似文献   

Effect of folic acid and vitamin B<Subscript>12</Subscript> administration on phenytoin induced toxicity in rats     

Itemobong S. Ekaidem  Monday I. Akpanabiatu  Friday E. Uboh  Offiong U. Eka 《Indian journal of clinical biochemistry : IJCB》2007,22(2):36-40

Folic acid and vitamin B₁₂ are very important vitamins needed for normal cellular metabolic activities. The effects of folic acid and vitamin B₁₂ on liver integrity of growing Wistar albino rats following therapeutic dose of phenytoin administration were investigated. The activities of serum AST, ALT, ALP were investigated. Serum total protein level and lipid profile were also measured as indices of biochemical changes. The ingestion of phenytoin alone in rats significantly reduced serum protein while AST, ALT activities incresed as compared to the control (P<0.05). Supplementation of phenytoin with oral administration of 70microgram/kg body wt of folic acid resulted in a significant reversal in serum total protein and suppression in serum AST and ALT activities. Vitamin B₁₂ supplementation did not afford any significant protection against the effect of phenytoin ingestion but rather phenytoin toxicity was exacerbated in this study. However, the combined effects of vitamin B₁₂ and folic acid ameliorated the effects of phenytoin on serum enzymes of experimental rats. The effect of combination of phenytoin with folic acid or folic acid and vitamin B₁₂ is an interesting finding. Supplementation of phenytoin with folic acid or combination of these vitamins may be recommended for the purpose of ameliorating the adverse biochemical changes which are associated with phenytoin therapy. Further work is ongoing to help elucidate the effects of phenytoin and these vitamins on oxidative stress inducing mechanism.  相似文献
