Metabolic Bone Profile of Healthy Adult North Indian Population from Chandigarh Urban Bone Epidemiological Study (CUBES)

We aimed to estimate metabolic bone profile in a large cohort of healthy, adult Indian population to generate reference standards of serum calcium, phosphate and alkaline phosphatase (ALP), 25 (OH) Vitamin D and iPTH, and also to find out the prevalence of Vitamin D deficiency in healthy population. Apparently healthy people in the age group of 20–80 years, residing in the union territory of Chandigarh were chosen. Fasting samples for serum calcium, phosphate, albumin, alkaline phosphatase (ALP), 25 (OH) D and iPTH were collected and were processed on the same day. We recruited 930 healthy subjects from different subsectors of Chandigarh. Final analysis was done for 915 subjects. Out of this, 530 (58%) were women and 385 (42%) were men. The study participants were divided into two groups, less than and more than 50 years for the men and pre and post-menopausal for the women. The serum calcium, phosphate, ALP and iPTH were significantly higher in the post-menopausal women compared to the pre-menopausal women. The median plasma 25 (OH) D in men and women was 12.5 ng/mL and 14.3 ng/mL, respectively. 25 (OH) D deficiency was seen in 65.4% of individuals. 25 (OH) D levels co-related negatively with iPTH levels (r = − 0.4, p < 0.0001), and showed an increasing trend with age. We have thus presented metabolic bone profile of healthy, adult north Indian population. These reference values can be used for diagnosis and monitoring of various MBDs. Vitamin D deficiency is still rampant in our population in spite of increasing awareness.     

运动训练对大鼠锌铜代谢及血清ALP,LDH活性影响的研究

通过对大鼠1次力竭性游泳和4周耐力性游泳训练后锌、铜代谢及血清碱性磷酸酶(ALP)、乳酸脱氢酶(LDH)活性变化的研究,结果发现:1)1次力竭性游泳运动导致大鼠锌、铜在体内重新分配,即通过血液运输,从骨骼肌向肝脏、心脏转移。2)4周耐力性游泳训练使大鼠机体增加对锌的储存,大鼠不表现锌缺乏,但大鼠体内铜储量下降,有导致缺乏可能。3)1次力竭性游泳运动后大鼠血清碱性磷酸酶、乳酸脱氢酶活性升高,但这些酶活性的升高与血清锌浓度上升没有明显相关关系。4)4周耐力性游泳训练使大鼠安静时血清乳酸脱氢酶活性升高,说明长期耐力运动有选择性导致某些血清酶活性升高的可能。     

Role of heat stable fraction of alkaline phosphatase as an adjunct to ca 125 in monitoring patients of epithelial ovarian carcinoma

Heat stable fraction (HSF) of alkaline phosphatase (ALP) was evaluated as an adjunct to CA 125 as a tumour marker for epithelial ovarian cancer in a follow-up study. In our study group 63.4% of patients had elevated HSF levels (≥10U/L) and 93.3% had elevated CA 125 levels (>35U/mL). The sensitivity of CA 125 and HSF was 93.3% and 63.3% respectively. The decline in the activity of HSF, over the pre-op levels was highly significant after the first (p=0.001) chemotherapy cycle and significant after the second and third cycles (p<0.029). Thereafter, HSF activity was almost undetectable. The decrease in CA 125 levels over the pre-op levels was significant after the first, second, third (p<0.001) and fourth (p<0.034) chemotherapy cycle. HSF can be used alone or as an adjunct to CA 125 in screening and monitoring patients of ovarian carcinoma especially in remote areas where sophisticated facilities are not available and in patients in which CA 125 levels are not raised preoperatively.     

4-氯-2,6-双吡啶双氧钒化合物降低1型糖尿病大鼠血糖的生物学作用

通过1型和2型糖尿病动物模型的研究发现过渡金属元素钒（V）具有降糖作用。有机钒化合物与无机钒相比,其副作用低、体内吸收率和生物利用度高。本文主要探讨了四价有机钒化合物4-氯-2,6-双吡啶双氧钒化合物（4-chloro-2,6-dipicolinatodioxovanadium(Ⅳ),V4dipic-Cl）对链脲佐菌素（STZ,55 mg/kg）诱导的1型糖尿病大鼠的生物学作用。大鼠通过自由饮水的方式口服V4dipic-Cl（0.5 mg/ml）8天。结果表明,V4dipic-Cl组的大鼠血糖和血清碱性磷酸酶（ALP）活性显著低于糖尿病对照组,并且其葡萄糖耐量水平得到明显改善。但有机配体H2dipic-Cl对糖尿病大鼠的血糖和血清ALP活性的影响不显著。结果提示V4dipic-Cl具有降低糖尿病大鼠的血糖,提高葡萄糖耐量和改善肝功能的作用。     

A Single Centre Prospective Study of Liver Function Tests in Post Liver Transplant Patients

Liver transplantation means surgical replacement of a diseased liver with a healthy liver. The survival rate used to be 30 % after 1 year and LTx was considered to be the last procedure when all medical or surgical intervention failed. Advances in donor organ preservation, surgical techniques, patient selection, immunosuppressive regimens and treatments for opportunistic infections all have contributed to substantially improve the survival rates. Despite substantial technological, medical and surgical advances, liver transplantation remains a complex procedure that is accompanied by significant morbidity and mortality. The post-operative outcome of each patient varies greatly depending on the patient’s pre- operative state, quality of the donated organ and the complexity of the surgery. Complications occur both immediately post transplant and in the long term. Most of the problems can be satisfactorily assessed with a panel of routine LFTs results of which are generated quickly, cheaply on the analyzer which operates 24 h. Liver Function Test identifies the presence of problem but not problem itself. Abnormal results can be meaningful only when used with clinical data, radiological findings. The study includes 75 post LTx patients in three groups adults (non ACR), Pediatrics and ACR. All recipients were on immunosuppressive therapy (tacrolimus, mycophenolate and methylprednisolone), antiviral (ganciclovir), antiprotozoal, antibacterial and antifungal (fluconazole). 5 mL of blood was drawn in plain vacutainer from the post LTx patients every day for 15 days and LFT and GGT was done. Routinely performed liver function tests correlates well with clinical complications involving liver in the transplant patients. Instead of daily testing, may be alternate day analysis of LFT should be sufficient for effective monitoring of patients. The total protein and albumin and the transaminases offer little help in monitoring LFT post LTx. The elevated levels of serum GGT and ALP may be related to chronic immune damage to the transplanted liver. Serum GGT and ALP can be used as early markers for diagnosing biliary complications and can be used to asses adequacy of endoscopic treatment in the group of patients presenting early. Thus, most of the problems can be satisfactorily assed with a panel of routine LFTs generated quickly, cheaply on analyzer which operates 24 h each day. However, it must be emphasized that LFTs may identify the presence of problems but not the problem itself and the abnormal results are meaningful only when correlated with other clinical information.
