Effect of Carica papaya (L) Leaves on Haematological Parameters in Ccl4-induced Wistar Albino Rats.

Aims: To investigate the effect of Carica papaya leaves on some haematological parameters (PCV, RBC, Hb, WBC and differential blood counts) were investigated. Place and Duration of Study: Department of Medical Biochemistry, Faculty of Basic Medical Sciences, College of Health Sciences, Niger Delta University, Wilberforce Island, Amassoma, Bayelsa-State, Nigeria, between. Methods: Thirty male albino rats were randomly allotted to five groups of six rats per group. Haemoglobin (Hb) was determined spectrophotometrically by the cyanomethaemoglobin method, Red blood cells (RBC), was estimated by haemocytometer, using adopted standard procedure. Group1 (negative control) were fed with 100% rat feed. Groups 2- 4 were pretreated with 10, 30 and 50% C. papaya L respectively, while Group 5 (normal control) received 100% rat feed. Rats in groups (1-4), were injected with CCl4 (0.5 ml/kg body weight in 0.5 ml olive oil) on the 29th day while rats in group 5 were not administered with CCl4 (normal control). Results: The results were statistically analyzed using one-way analysis of variance (ANOVA). There were significant increases (p≤ 0.05) in the levels of Hb, PCV, RBC, lymphocytes and decreased WBC and neutrophils in rats in group 5 (normal control) as against the negative control (group 1). Rats groups pretreated with 10, 30 and 50% Carica papaya (groups 2, 3 and 4 respectively), showed significant increased (p≤ 0.05) PCV, RBC and Hb levels, when compared with untreated rats (group 1). Rats that were administered with CCl4 only (negative control), showed significant increases (p≤ 0.05) in the levels of WBC and neutrophils. However, incorporation of 10, 30 and 50% Carica papaya in groups 2, 3 and 4 respectively, significantly decreased the levels of WBC and neutrophils, when compared with rats in untreated group 1. Monocytes levels significantly increased (p≤ 0.05) in rats pre-treated with 30% and 50% Carica papaya (groups 3 and 4 respectively). While, there was zero level of basophils in all the groups. Conclusion: Carica papaya L, may therefore possess and confer erythropoietic properties on rats pretreated groups as evident in the increased levels of Hb, PCV, RBC and lymphocytes.

Living kidney donor transplants over a 16-year period in South Africa: a single center experience

BACKGROUND:Kidney transplantation is the treatment of choice for end-stage renal disease (ESRD). The number of patients on the waiting list is increasing due to an imbalance between organ supply and demand. This has led to an increase in the number of living donor transplants in most parts of the world. The benefits to the recipients must, however, be weighed against the risks to the donors. Long-term follow-up of the donors is therefore imperative to ascertain the risks of living kidney donation.MATERIALS AND METHODS:We reviewed the records of 571 potential living kidney donors (PLDs) in Johannesburg hospital over a 16-year period between 1990 and 2005.RESULTS:There were 1030 kidney transplants during this period, with 800 cadaveric and 230 actual living donor (ALD) transplants. There were 571 PLDs; however, 341 (59.7%) withdrew or were withdrawn because of medical and non-medical reasons. Among the 230 ALDs, the mean age of the donors was 35.2 ± 8.3 years; 55% were females; 24% were Blacks. Eighty-five percent were related to the recipients while 15% were unrelated. Mean duration of follow-up was 8.6 ± 6.4 years. The pattern of post-donation follow-up was excellent in 29.7%, adequate in 34% and unacceptable/poor in 36.3%, based on the number of clinic visits post-donation. Hypertension was noted in 24% of the donors during long-term follow-up. Three of the donors also developed significant microalbuminuria.CONCLUSION:There is a need to encourage living kidney donation, especially amongst the Black populations, and to emphasize the value and significance of post-donation follow-up visits to all potential donors

Preliminary Investigation of a Herbal Soap Incorporating Cassia Senna(L) Roxb Leaves and Ageratum Conyzoides Linn Whole Plant Powders

In traditional medicine practice the locally made soap is a vehicle for drug application and drugs are usually incorporated in powder form. Many herbal soaps being made incorporate the extract of the medicinal plant; but this makes the soap very expensive and not easily produced for the use of the majority of people. This study investigates the activity of a herbal soap incorporating two medicinal plants ; Senna alata (L) Roxb (Ceasalpinaceae) and Ageratum conyzoides Linn(Asteraceae) which are well known for their use in the treatment of skin diseases and their antimicrobial activity; comparing it to the extracts of the plants. The study also determines the optimum concentration of the herbs to be incorporated into the soap. Three soaps containing 3;5 and 8of the moderately fine powder of the two medicinal plants were prepared using the normal cold method for preparing hand and body soap with NaOH and Palm kernel oil. Extract of the two plants was prepared by cold extraction with methanol and concentrated in vacuo. The soaps and the extract were tested for antimicrobial activity against typed organisms and clinical isolates; gram negative; gram positive organisms and fungi. The results showed that the soap at 5herbal content was optimal. The soaps showed activity against mainly the gram positive organisms and fungi. The activity of the extract was not different from that of the soaps and therefore shows no advantage in using the extracts to prepare the herbal soap

Lipid Profile in Sickle Cell Disease Patients with Chronic Kidney Disease

Background: Dyslipidaemia is reported to occur in patients with sickle cell disease as well as patients with chronic kidney disease irrespective of the haemoglobin genotype. This study aimed at evaluating lipid profile in subjects with sickle cell anaemia (HbSS); sickle cell trait (HbAS) and normal haemoglobin genotype (HbAA); and comparing the lipid parameters between sickle cell disease patients with and those without chronic kidney disease. Methods: A total of 66 patients with chronic kidney disease: 26 HbAA; 24 HbAS and 16 HbSS and 60 apparently healthy controls were recruited for the study. Lipoproteins; urea; creatinine; estimated glomerular filtration rate and electrolytes were determined using standard procedures in both patients and controls. Results: The mean total cholesterol; low density lipoproten cholesterol and high density lipoproten cholesterol in stable HbSS subjects were significantly lower (p

Detection of helicobacter pylori infection and upper gastrointestinal disorders among Zagazig university hospitals waste collectors: a comparative cross- sectional study

Hospital work, involving direct patient contact and poor sanitary conditions, constitutes a major risk factor for acquisition of H. pylori infection. 1] determining the prevalence and occupational risk of, pylori infection among hospital waste collectors, 2] identifying some of its associated risk factors, 3] investigating the validity of some non-invasive tests for the diagnosis of H. pylori infection in comparison with the gold-standard invasive test, esophagogastroduodenoscopy with biopsy, 4] comparing the diagnostic performance of salivary H. pylori IgG with that of serum H. pylori IgG, and 5] determining the percentages of upper gastrointestinal [GIT] symptoms and the endoscopic findings among hospital waste collectors and assessing their relation to H. pylori infection. This comparative cross-sectional study was conducted on 78 hospital waste collectors and 78 security and administrative workers from Zagazig University Hospitals as a control group. All participants filled pre-constructed questionnaires and were subjected to H. pylori stool antigen and serum and salivary anti-H. pylori IgG tests; while only 110 workers underwent esophagogastroduodenoscopy with biopsy and rapid urease test. The results revealed absence of significant occupational risk of H. pylori infection acquisition among hospital waste collectors compared to the controls. Moreover, Male sex, smoking habit, low socioeconomic status, poor personal hygiene, and family history of upper GIT complaints were the risk factors significantly associated with active H. pylori infection. Fecal antigen test had the highest sensitivity, specificity, positive, and negative predictive values for the diagnosis of H, pylori infection compared to the other non-invasive tests. Moreover, there was a fair degree of agreement between salivary and serum H. pylori IgG tests regarding their diagnostic performance [0.34]. Also, absence of statistical significant differences between both studied groups regarding the percentages of upper gastrointestinal symptoms and different endoscopic findings was revealed. Finally, current H. pylori infection was found to be significantly associated with different types of gastritis; however, normal mucosa by endoscopy didn't exclude the presence of H, pylori infection. So, improving the overall standard of living in our country, environmental sanitation, introducing effective anti-infective sanitary regulations at work, mass screening through either stool antigen or serum IgG or salivary IgG tests to detect infected persons, and proper treatment of infected persons are mandatory

Antibiotic resistance of helicobacter pylori from patients in Ile-Ife, South-west, Nigeria

Background: Helicobacter pylori has become recognized as a major cause of gastroduodenal diseases in man. Evidence indicates that once acquired; H. pylori persists; usually for life unless eradicated by antimicrobial therapy. Over the past few years; we have accumulated some knowledge of the epidemiology of H. pylori in Ile-Ife; South-West Nigeria. In one collaborative study; we detected H. pylori in 195 (73) patients referred for endoscopy at Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC). Furthermore we have observed a variegated gastric inflammatory response and atrophy including atrophic pangastritis but are yet to demonstrate MALToma in any of our patients. In addition we have demonstrated that dental plaque is a possible source of gastric H. pylori infection and such an endogenous source could account for difficulty in eradication leading to re-infection. Presently; infected patients are treated with standard combination therapy made up of amoxycilin and ciprofloxacin with a proton pump inhibitor /bismuth. Reports however have shown that the incidence of antimicrobial resistance in Helicobacter pylori is a growing problem and which has been linked with failures in treatment and eradication. Given this situation it has become necessary to have information about the susceptibility of isolates to particular antimicrobial agents before the selection of an appropriate treatment regimen. Objectives: More recently; we sought to study antimicrobial susceptibility of locally isolated H. pylori strains. Methods: We subjected 32 isolates to antimicrobial susceptibility testing against seven agents. Results: All the isolates showed multiple acquired antimicrobial resistance as they were all resistant to amoxicillin; clarithromycin; metronidazole; while 29/31; 27/31 showed resistance to rifampicin and tetracycline respectively. Five (15.6) of these isolates showed resistance to ciprofloxacin. Conclusions: Our findings suggest that H. pylori strains isolated within our study environment have acquired resistance to all the commonly pres-cribed antibiotics. On the basis of the findings it would be necessary to re-evaluate the eradication treatment regime in our setting
