Abstract

Low-molecular-weight (3-6 kDa) water-soluble chitosan was obtained by enzymatic depolymerization. Hydrolysis of crab chitosan was induced by O-glycoside hydrolase (EC 3.2.1), an extracellular chitinolytic complex from Bacillus sp. 739. The optimum conditions for hydrolysis were found (sodium-acetate buffer, pH 5.2; 55 degrees C; an enzyme/substrate ratio 4 U/g chitosan; 1 h).

Pharmacokinetics of 5-fluorouracil in mutant Nagase analbuminemic rats: faster metabolism of 5-fluorouracil via CYP1A.

It has been reported that plasma albumin concentrations were significantly lower in cancer patients than those in the healthy volunteers, and the expression and mRNA level of hepatic microsomal cytochrome P450 (CYP) 1A2 increased in mutant Nagase analbuminemic rats (NARs). After intravenous administration of 5-fluorouracil at a dose of 30 mg/kg to NARs, the time-averaged nonrenal clearance (Clnr) of the drug was significantly faster than the controls (51.3 versus 28.8 ml/min/kg), possibly due to an increase in the expression and mRNA level of CYP1A2 in NARs. In order to determine whether 5-fluorouracil is metabolized via CYP1A2 in male Sprague-Dawley rats, the rats were pretreated with 3-methylcholanthrene (a main inducer of CYP1A1/2 in rats). The Clnr of 5-fluorouracil was significantly faster (34.3 versus 27.3 ml/min/kg) in rats pretreated with 3-methylcholanthrene. The aforementioned data indicate that CYP1A is involved in the metabolism of 5-fluorouracil in rats.

Effect of sulodexide on albuminuria, NAG excretion and glomerular filtration response to dopamine in diabetic patients.

BACKGROUND: Albuminuria is the best and most readily available marker for glomerular damage and progressive renal function loss in patients with diabetic nephropathy. Recently, administration of the oral glycosaminoglycan sulodexide (a mixture of 80% fast-moving heparin and 20% dermatan sulphate) was shown to effectively decrease albumin excretion rate in diabetics with nephropathy. AIMS: To evaluate whether the hypoalbuminuric effect of sulodexide is associated with improvement of the renal vascular or tubule function. METHODS: Forty-five type 1 diabetic patients, affected by diabetic nephropathy with albuminuria for at least 5 years, were randomly allocated to sulodexide or untreated. Those allocated to sulodexide were given 100 mg of sulodexide daily for 120 days. Renal vascular function (DIR) and N-acetyl-beta-D-glucosaminidase (NAG) excretion were estimated before and at the end of the study, the former in thesulodexide group only. DIR was measured as two Cr(cl) lasting 120 min (before and during 2 mug/kg b.w. i.v. dopamine). RESULTS: The analysis of trends during the study demonstrated a marked reduction of albuminuria in the sulodexide group (from 126.1 +/- 15.41 to 93.6 +/- 13.7 mg/day). DIR rose from 13.2 +/- 2.1% to 15.44 +/- 1.9% (relative increase: +16.9%), and NAG excretion showed a decreasing trend decreased in the sulodexide group only (from 5.1 +/- 0.62 to 4.7 +/- 0.40 U/g(creat)). CONCLUSION: The findings presented in this study indicate for the first time that orally available sulodexide may favorably affect the renal vascular function in type 1 diabetic patients with nephropathy and microalbuminuria. The effect of sulodexide on NAG is strongly influenced by the baseline NAG values, with a significant NAG reduction in the patients with the highest baseline NAG values.

Preventive effect of naringin on cardiac markers, electrocardiographic patterns and lysosomal hydrolases in normal and isoproterenol-induced myocardial infarction in Wistar rats.

Diets rich in natural antioxidants are associated with reduced risk of heart diseases. This study was aimed to evaluate the preventive role of naringin on cardiac troponin T (cTnT), lactate dehydrogenase (LDH)-isoenzyme, cardiac marker enzymes, electrocardiographic (ECG)-patterns and lysosomal enzymes in isoproterenol (ISO)-induced myocardial infarction (MI) in male Wistar rats. Rats subcutaneously injected with ISO (85mg/kg) at an interval of 24h for 2 days showed a significant increase in the levels of cTnT, intensity of the bands of LDH-isoenzyme (LDH1 and LDH2) and the activities of cardiac marker enzymes such as creatine kinase-MB (CK-MB), creatine kinase (CK), LDH, aspartate transaminase (AST) and alanine transaminase (ALT) in serum with subsequent decrease in the activities of CK, LDH, AST and ALT in the heart and alterations in ECG-patterns. The activities of lysosomal enzymes (beta-glucuronidase, beta-N-acetyl glucosaminidase, beta-galactosidase, cathepsin-B and cathepsin-D) were increased significantly in serum and the heart of ISO-induced rats, but the activities of beta-glucuronidase and cathepsin-D were decreased significantly in the lysosomal fraction of the heart. Pretreatment with naringin (10, 20 or 40mg/kg) daily for a period of 56 days positively altered the levels of cTnT, intensity of the bands of the LDH1 and LDH2-isoenzyme and the activities of cardiac marker enzymes, ECG-patterns and lysosomal hydrolases in ISO-induced rats. Thus, naringin possess cardioprotective effect in ISO-induced MI in rats.
