UNLABELLED: Contrary to the well-known features of diabetic nephropathy (DNP) in type-1 diabetic patients (pts), the prevalence, course and risk factors of DNP in in type-2 diabetic pts are not clear. The aim of the present study was to assess the prevalence of microalbuminuria (MA) and macroalbuminuria (MAA), their relationship with other diabetic complications and with some known cardiovascular risk factors in 200 in type-2 diabetic pts (100 females and 100 males). 68 pts (33%) were normalbuminuric (NA), 55 (27.5%) had MA and 77 (38.5%) had MAA. There was no significant difference among these three groups in age, BMI or the time actually elapsed since the diabetes and hypertension were diagnosed. BMI was high in each group (28.8 +/- 5.29, 28.0 +/- 5.2 and 29.8 +/- 4.6 kg/m2 mean +/- SD). 65% of pts with NA, 77% of those with MA and 81% of pts with MAA had hypertension. MAA pts were more frequently smokers and former smokers, than MA and NA pts (56% vs 32% and 22%). Average GRF values (ml/min/1.73 m2) were 71.9 +/- 26.8 in NA pts, 82.3 +/- 36.8 in MA pts and 56.3 +/- 32 in MAA pts. There was no significant correlation between the urinary albumin excretion (UAE) and glycemic control, serum (se) cholesterol and se HDL cholesterol. At the same time UAE showed a significant positive correlation with se trigliceride (P < 0.01), se uric acid (P < 0.01) and se creatinine (P < 0.01) while a significant negative correlation was found with GFR (P < 0.01). Diabetic non-proliferative retinopathy (RP) was detected even in NA pts (27%) while 51% of MAA pts were without RP. 56% of NA pts, 57% of MA pts and 93% of MAA pts had macroangiopathy. CONCLUSIONS: (1) renal function can be impaired even in type-2 diabetic pts with NA and MA, (2) well-known cardiovascular risk factors seem to have a close relation with renal damage in type-2 diabetes (3) renal lesions in type-2 diabetic pts may be caused by diseases other than diabetes (e.g. arteriosclerosis, hypertension) (4) unlike in type-1 diabetes, where the strict glycemic control is the main preventive factor of DNP, in type-2 diabetes, the control of hypertension, hyperlipidemia, obesity, hyperuricemia may have priority.

Effect of dose increase or cimetidine co-administration on albendazole bioavailability.

The low bioavailability of albendazole affects the therapeutic response in patients with echinococcosis. Cimetidine co-administration is reported to improve bioavailability. To analyze the assumed dose-dependent bioavailability of albendazole, we administered 5 to 30 mg/kg albendazole to 6 male volunteers in a randomized cross-over study. To assess the effect of cimetidine (10 mg/kg twice daily), the drug was given with albendazole (20 mg/kg). A dose-dependent bioavailability was not observed. This was due to inter-individual variability of the maximal concentration (Cmax 38%-72%) of albendazole sulphoxide (ABZSX), the active metabolite of albendazole. Cmax was 0.21+/-0.14 mg/L after 5 mg/kg and 0.39+/-0.19 mg/L after 30 mg/kg albendazole (P = 0.217). Cimetidine tended to decrease Cmax by 52% (P = 0.109) and significantly inhibited ABZSX breakdown as indicated by the prolongation of ABZSX elimination half-life from 7.4+/-3.3 hr to 19.0+/-11.7 hr (P = 0.028). Remarkably, the inter-individual variability of Cmax was significantly lower during cimetidine co-administration: 14% versus 72%.

The metabolism of EGYT-475, a new antidepressant agent, in rats.

The metabolites of EGYT-475 excreted by the kidney were studied in rats using radioactive analogues of the compound tested. 40% of the total radioactivity was found in rat urine which was collected over 48 h, pooled, centrifuged, membrane-filtered, and from which the metabolites were separated by combined chromatographic procedures or extracted after acidic hydrolysis. Gas chromatographic and GC/MS studies showed that 31.1% of the radioactivity found in urine proved to be picolinyl-piperazine, 3.7% was N-benzyl-piperazine and 28.5% of it was picolinic acid. Hippuric acid accounted for 53.2% of the radioactivity of the acid hydrolyzed urine.

Atropine stereotypy and its inhibition by intracaudate triperidol in the rat.

One component (rearing) of the stereotyped behavior of the rat was quantitated using erigometer, a new device developed in this laboratory. Intraperitoneal injection of atropine, but not methylatropine, caused dose-related stereotyped behavior in the rat and this effect was antagonized by intracaudate injection of triperidol in a dose-related manner. It is concluded that stereotypy can be evoked also in the case when the striatal dopaminergic tone is normal or even below normal: it is the equilibrium of the striatal cholinergic-dopaminergic systems which must be shifted towards dopamine, which is necessary for the development of this behavioral manifestation.

Nitric oxide in IgA nephropathy patients with or without hypertension.

Nitric oxide (NO) is claimed to have a role in the pathogenesis of immune-mediated glomerulonephritis and in the regulation of blood pressure (BP). NO rapidly converts to NO2-/NO3- which is excreted in the urine. We determined the daily NO2-/NO3- excretion in 26 IgA nephropathy (NP) patients and 20 healthy controls, recording the BP in each. There was no difference in NO2-/NO3- excretion between IgA NP patients and controls (999.1 +/- 66.8 vs. 1,051.2 +/- 53.0 mumol/day). The urinary excretion of NO2-/NO3- in IgA NP patients whose mean diastolic BP remained above 85 mm Hg in spite of antihypertensive therapy, was significantly decreased (n = 8; 734.38 +/- 87.83 mumol/day; p < 0.05). There was a significant inverse correlation between mean diastolic BP and urinary NO2-/NO3- (p < 0.006). NO2-/NO3- excretion decreased with aging (p < 0.01) in IgA NP patients, but not in controls. The fact that there was no difference between the urinary NO2-/NO3- excretion of IgA NP patients and controls argues against the idea that NO production in immune-mediated IgA NP can be increased. The decrease of urinary NO2-/NO3- in hypertensive and in older IgA NP patients may be correlated with the impaired NO production of the endothelium.

Investigation of the chemiluminescence associated with phagocytic and intracellular killing activity of human polymorphonuclear leucocytes and monocytes.

The chemiluminescence associated with phagocytic and intracellular killing activity of human polymorphonuclear leucocytes and monocytes was investigated. A significant, opsonization-dependent increase in photon emission of polymorphonuclear leucocytes and monocytes was observed induced by engulfment of opsonized, heat-killed and living fungi (Saccharomyces cerevisiae), aggregated gamma globulin, latex and India ink particles. Mononuclear cells displayed only minimal enhancement of photon emission after incubation of various particles. It is suggested that the method can be used in clinical practice as a test of phagocytotic and intracellular killing function.
