It has been found that honey ameliorates cardiovascular risk factors in healthy individuals and in patients with elevated risk factors. The present study investigated the effect of natural honey on total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triacylglycerole, C-reactive protein (CRP), fasting blood glucose (FBG), and body weight in overweight individuals. There were 55 patients, overweight or obese, who were randomly recruited into the study and assigned into two groups: control group (17 subjects) and experimental group (38 subjects). Patients in the control group received 70 g of sucrose daily for a maximum of 30 days and patients in the experimental group received 70 g of natural honey for the same period. In the control and experimental groups, body weight, body mass index, body fat weight, total cholesterol, LDL-C, HDL-C, triacylglycerole, FBG, and CRP were measured before treatment and at day 31 after the commencement of treatment. Results showed that honey caused a mild reduction in body weight (1.3%) and body fat (1.1%). Honey reduced total cholesterol (3%), LDL-C (5.8), triacylglycerole (11%), FBG (4.2%), and CRP (3.2%), and increased HDL-C (3.3%) in subjects with normal values, while in patients with elevated variables, honey caused reduction in total cholesterol by 3.3%, LDL-C by 4.3%, triacylglycerole by 19%, and CRP by 3.3% (p < 0.05). It is our conclusion that consumption of natural honey reduces cardiovascular risk factors, particularly in subjects with elevated risk factors, and it does not increase body weight in overweight or obese subjects.

This study was carried out to monitor the effect of oral supplementation of vitamin C on various semen parameters in oligospermic, infertile, otherwise healthy individuals. Various semen parameters, including sperm motility, sperm count, and sperm morphology, were studied before and after the vitamin C treatment. A total of 13 infertile patients were included. Their ages ranged between 25 and 35 years. They had no genital infection or varicocele. Physical examination and other routine laboratory investigations were normal. General semen analysis revealed oligozoospermia (mean sperm count was 14.3 +/- 7.38 x 10(6) sperms/mL, mean sperm with normal morphology was 43 +/- 7.87%, and mean sperm motility was 31.2 +/- 9.61%). Testicular biopsy was not done. These patients received in an open trial of 1,000 mg of vitamin C twice daily for a maximum of 2 months. Results showed that the mean sperm count was increased to 32.8 +/- 10.3 x 10(6) sperms/mL (P < .001) after 2 months of vitamin C intake. The mean sperm motility was increased significantly to 60.1 +/- 8.47% (P < .001), and mean sperms with normal morphology increased significantly to 66.7 +/- 4.77% (P < .001). This study showed that vitamin C supplementation in infertile men might improve sperm count, sperm motility, and sperm morphology and might have a place as an additional supplement to improve the semen quality towards conception.

The objectives were to assess the effects of various diets, including total food restriction with 50% honey feeding, total food restriction with 50% dextrose feeding or adlibitum (control group) commercial regular diet, on the hematology and biochemical variables, and to assess the effects of the various diets on the influence of acute blood loss on the same parameters. Thirty Sprague-Dawley albino rats were divided into three groups, 10 rats each: group A, fed a commercial regular diet; group B, total food restriction with 50% dextrose feeding; and group C, total food restriction with 50% honey feeding. After 8 days of feeding, rats were subjected to acute blood loss (6 ml/kg) and blood investigations were performed. After acute blood loss, the same feedings were continued for a further 8 days and the blood tests were repeated at day 8 post-bleeding. Total food restriction with 50% dextrose feeding compared with commercial regular diet reduces hematological and biochemical variables. Total food restriction with 50% honey feeding compared with total food restriction with 50% dextrose feeding causes a greater reduction in fasting blood glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and triacylglycerol. Acute blood loss causes elevation of white blood cells, lymphocyte percentage, fasting blood sugar, blood urea nitrogen, alkaline phosphatase and triacylglycerol, and a reduction in serum albumen, protein, cholesterol, AST, serum creatinine and hemoglobin; the results are significant (P<0.05) concerning fasting blood glucose, AST, alkaline phosphatase, serum albumin and protein. A significant reduction in fasting blood glucose, white blood cells, BUN, AST, ALT, alkaline phosphatase and triacylglycerol, and a significant elevation of hemoglobin and serum albumin are obtained after acute blood loss in rats on total food restriction with 50% honey feeding as compared with the other two groups. Total food restriction with 50% honey feeding increases serum albumin, serum protein, fasting blood glucose, and causes lower reduction in hemoglobin as compared with the other groups. Conclusively, honey feeding during total food restriction significantly modifies and ameliorates biochemical and hematological changes observed after acute blood loss. This will pave the way to use honey as part of bleeding management and during a food restriction regimen.

The objective was to assess the effects of commercial regular diet as control, total food restriction with honey, commercial regular diet with dextrose, or total food restriction with dextrose, on blood variables after carbon tetrachloride (CCl4) administration. Sprague Dawley albino rats were divided into four groups, 10 rats each; Group 1 rats were on commercial regular diet, Group 2 rats were on commercial regular diet with 50% dextrose, Group 3 rats were on total food restriction with 50% dextrose, and Group 4 rats were on total food restriction with 50% honey. Rats in all the groups were i.m. administered CCL4 (2.4 mL kg b. wt.-1). Blood tests including ALT, AST, serum albumin, serum protein, BUN, blood glucose (BG), hemoglobin (Hb), and white blood cell (WBC) were performed before CCl4 administration and repeated after 48 and 96 h of post-injection. In Group 1, CCl4 caused significant elevation in AST and ALT, and decrease in BS, WBC, and BUN; lower elevation in AST and ALT at 48 h and decreased AST and ALT at 96 h were obtained when dextrose was added to commercial regular diet (Group 2). Using dextrose alone (Group 3), though there was significant elevation of AST and ALT and decrease in BUN and WBC as compared to baseline values, significant decrease in ALT, AST, and BUN as compared to control was obtained. During absolute honey feeding (Group 4), elevation in AST and ALT obtained, following CCl4 administration was significantly less than the values obtained in all other groups; with lower elevation in AST and ALT as compared to baseline values. Honey increased serum albumin, serum protein, BG, and caused lower reduction in Hb. Conclusively, exclusive honey feeding (50% concentration) significantly modifies and ameliorates biochemical and hematological changes obtained after CCl4 injection.
