An extended chemical analysis of gallstone

Chemical composition of gall stones is essential for aetiopathogensis of gallstone disease. We have reported quantitative chemical analysis of total cholesterol bilirubin, calcium, iron and inorganic phosphate in 120 gallstones from haryana. To extend this chemical analysis of gall stones by studying more cases and by analyzing more chemical constituents. A quantitative chemical analysis of total cholesterol, total bilirubin, fatty acids, triglycerides, phospholipids, bile acids, soluble proteins, sodium potassium, magnesium, copper, oxalate and chlorides of biliary calculi (52 cholesterol, 76 mixed and 72 pigment) retrieved from surgical operation of 200 patients from Haryana state was carried out. Total cholesterol as the major component and total bilirubin, phospholipids, triglycerides, bile acids, fatty acids (esterified), soluble protein, calcium, magnesium, iron, copper, sodium, potassium, inorganic phosphate, oxalate and chloride as minor components were found in all types of calculi. The cholesterol stones had higher content of total cholesterol, phospholipids, fatty acids (esterified), inorganic phosphate and copper compared to mixed and pigment stones. The mixed stones had higher content of iron and triglycerides than to cholesterol and pigment stones. The pigment stones were richer in total bilirubin, bile acids, calcium, oxalate, magnesium, sodium, potassium, chloride and soluble protein compared to cholesterol and mixed stones. Although total cholesterol was a major component of cholesterol, mixed and pigment gall stone in Haryana, the content of most of the other lipids, cations and anions was different in different gall stones indicating their different mechanism of formation.     

Changes in serum copper levels in patients with malignant diseases undergoing radiotherapy

Present study repots changes in serum copper levels (SCL) in various neoplastic diseases undergoing radiotherapy. We estimated SCLs in 140 individuals comprising of 90 previously untreated patients with various malignancies and 50 healthy controls. Patients received radiation in doses of 40–70 Gy in 4–7 weeks. SCLs were again estimated in patients following irradiation. The mean SCL was significantly higher (P<0.001) in cancer patients as compared to healthy controls. It declined significantly (P<0.001) following irradiation. However, it remained significantly higher as compared to healthy controls (P<0.01). Highest fall in SCL was seen in complete clinical responders and least in non-responders to radiation treatment. Serial estimation of SCLs may be useful in the treatment monitoring of the neoplasms undergoing radiation treatment.     

A study of serum lipid profile part-1: Establishment of normal reference values of serum lipid levels in healthy vegetarian population of Gujarat

Fasting samples of 1329 apparently healthy vegetarian Gujarati population were tested for total cholesterol, triglycerides and three major fractions of lipoproteins, i.e. high density lipoproteins, low density lipoproteins and very low density lipoproteins. All the values showed marked increase with the age. Except for serum triglycerides, values differ in males and females in the age group of above 45 years. Compared to Northern Indian population low density lipoprotein and high density lipoprotein values were higher, but values of triglycerides and very low density lipoproteins were lower. There is no significant difference in total cholesterol values. Compared to Southern Indian population low density lipoprotein and very low density lipoprotein values were higher but values of triglycerides, total cholesterol and high density lipoprotein were lower. All serum lipid values were significantly lower than the Westem population. The range of values for both the sexes is presented for different age groups.

Study on the serum levels of soluble intercellular adhesion molecule-1 (sICAM-1) in patients withHelicobacter pylori infection

Objective: To evaluate the interaction between serum levels of soluble intercellular adhesion molecule-1 (sICAM-1) andHelicobacter pylori (H. pylori) infection in patients with chronic gastritis and peptic ulcer. Methods: The serum levels of sICAM-1 in 205 patients with chronic gastric diseases were detected by ELISA method and the status ofH. pylori was determined by histologic examination, RUT,¹⁴C-UBT, and serology. The sera obtained from 18 healthy volunteers served as controls. Results: The serum levels of sICAM-1 were significantly higher in patients withH. pylori positive than those of H. pylori negative (889.43±32.52 ng/ml vs. 747.07±30.45 ng/ml,P<0.05). The serum levels of sICAM-1 in patients with mild, moderate and severe infection ofH. pylori were 841.68±72.36 ng/ml, 905.43±37.59 ng/ml and 1012.54±49.34 ng/ml, respectively (P<0.05). The serum levels of sICAM-1, proved to be significantly correlated with the density ofH. pylori colonization in gastric mucosa (r _s=0.316,P<0.001). The serum levels of sICAM-1 in patients with chronic gastritis and peptic ulcer were significantly higher than those in healthy controls (P<0.05). Conclusions: These results indicated thatH. pylori infection up-regulates the expression of sICAM-1.

当归对肝损伤模型小鼠部分糖代谢指标的影响

50只小鼠随机分成5组,I～V组分别对照组、肝损伤模型组和当归剂量组（低、中、高荆量）。Ⅲ～V组分别按5／kg、10g／kg,2％／kg皮下注射当归注射液,I、Ⅱ组注射等量的生理盐水,连续5d。末次给药后2h,Ⅱ～V组腹腔注射0．1％四氯化碳石蜡油溶液（10mL／kg）,24h后处死小鼠测定肝指数、血糖水平和肝糖原、肌糖原含量。结果表明,模型组及当归各剂量组的小鼠肝指数与对照组差异不显著（P〉0．05）。模型组血糖水平显著降低,肝糖原、肌糖原含量显著提高（P〈0．01）,低、中剂量的当归表现对抗作用,低剂量作用显著（P〈0．01）。表明肝损伤模型小鼠部分糖代谢指标出现异常变化,低剂量的当归对此具有明显的保护作用。
