The continuous fluctuation in power supply in some developing countries has been suggested to be one of the contributing factors that affect stored experimental blood samples leading to errors in laboratory results. The study was therefore aimed at evaluating the effect of vitamin-E stored blood samples on Malondialdehyde (MDA) and protein concentrations with a view to suggesting a way of reducing errors in laboratory results that are due to oxidation. MDA was determined using the method of Das et al. (1990) while Biuret's method as described in Amadi et al. (2004) was used to determine the protein concentration. The results obtained show that MDA concentration in the blood sample without vitamin E increased during storage from day 1 (80% TBARS) today 4 (233% TBARS) while in the sample stored with vitamin E, the concentration of MDA decreased slightly during storage from day2 (80% TBARS) today (79% TBARS). The protein concentration in the samples without vitamin E decreased during storage from day 1 (2.5±0.08 g/dl) today 4 (1.7±0.09g/dl) while the concentration of protein in the sample stored with vitamin E, showed no significant increase or decrease from day 2 (2.5±0.03g/dl) today 4 (2.4±0.01g/dl). From the results of the study, it is therefore strongly suggested that vitamin E should be added to blood samples before storage considering the inconsistent power supply in developing countries. This will reduce the effect of oxidation and thus minimize errors in laboratory results.Keywords

Anaemia is an independent risk factor for disease progression and death in persons with HIV infection. The prevalence and severity of anaemia was therefore correlated amongst 300 Cameroonian adult males and females who were diagnosed with the HIV infection at the Bamenda Regional Hospital. Four different haemoglobin concentrations were used as cut off points to categorize anaemia into mild anaemia (Hb ≤ 10g/dl); clear - cut anaemia (Hb ≤ 9g/dl); severe anaemia (Hb ≤ 7g/dl) and critically severe anaemia (Hb ≤ 5g/dl). A cell - Dyn 3200 blood analyzer was used to determine the haemoglobin concentration of the different groups of patients. Results obtained showed that the mean haemoglobin concentration of the HIV infected males (10.08 ± 0.4g/dl) significantly decreased (p<0.05) compared to the mean haemoglobin concentration of the HIV free control (14.0 ± 0.14g/dl). The mean haemoglobin concentration of the HIV infected females (8.76 ± 10.5g/dl) also decreased significantly (p<0.05) compared to the HIV free control (12.1 ± 0.8g/dl). The prevalence of mild anaemia, clear - cut anaemia, severe anaemia and critically severe anaemia were 43.3%, 40%, 4.7% and 0% in males and 25.3%, 60%, 4.7% and 10% in females respectively. The results obtained from this study indicates that the severity of anaemia in higher in HIV infected adult females than adult males attending the Bamenda Regional Hospital.Keywords

Poisonings from household chemicals such as cleaning products and cosmetics are common occurrences and can cause acute respiratory infections and cancer. This study was therefore aimed at evaluating the level of prevention and management of accidental poisoning from household chemicals in the Nkwen Area in Bamenda, Cameroon. A cross-sectional population based descriptive study was undertaken in miles three and four Nkwen, Bamenda in which 110 households were randomly selected to take part. The evaluation was carried out by the use of a questionnaire survey. From the results obtained, detergents and cosmetics were the most available chemicals used in these areas, with cosmetics contributing to 32.22% of poisoned cases while detergents contributed to 51.11% of the poisoned cases. It was also found that most of the poisoned cases were not taken to the hospital. In conclusion, this study had shown that the level of prevention and management of accidental poisoning from household chemicals in the study areas were generally poor.Keywords

The aim of this study was to assess the practice of radiation protection and compare it with the stated norms of radiation protection. A cross - sectional hospital based descriptive design was undertaken in four hospitals in Yaounde, Cameroon in which all the technologists (17) working in the x - ray department of the selected hospitals took part in the study. The assessment was carried out by the use of a questionnaire survey. From the results obtained, all the hospitals had lead aprons and shields but only one hospital gonad shield and lead gloves. 47.06% had been trained for at least three years. Radiation protection supervisors were present in two of the four hospitals but only one hospital had a warning red light in good working condition. In conclusion radiation protection in conventional radiography is not properly practiced as not all norms are respected and therefore remains a problem that needs to be solved.Keywords
