Evaluation of some biomarkers of inflammation in male Albino Wistar rats following ingestion of Nigerian Bonny Light Crude Oil (NBLCO) and the effect of antioxidant supplementation was the focus of this study. Forty-eight adult male Albino Wistar rats weighing 150 - 180 g were randomly divided 8 per group into: group I (control) oral gavaged 3 ml/kg of normal saline;group II received 3 ml/kg of NBLCO;groups III, IV and V received in addition to 3 ml/kg of NBLCO 1 ml/kg vitamin C, vitamin E and 3 ml/kg of honey bee respectively;group VI received 3 ml/kg of honey. After 28 days of treatment, all animals were anaesthetized with chloroform and blood collected by cardiac puncture for analysis. Results showed that NBLCO administration significantly increased erythrocyte sedimentation rate and C-reactive protein while supplementation with antioxidant significantly reversed such effects (p < 0.05). NBLCO significantly reduced platelets and fibrinogen levels compared with the control group (p < 0.05). Interestingly, the vitamin supplementation significantly reduced platelets and fibrinogen levels compared to group II (NBLCO) (p < 0.05). Honey supplementation on the other hand significantly reduced platelets and fibrinogen compared to group II (NBLCO) (p < 0.05). From the results obtained it is concluded that ingestion of NBLCO has the potential to induce development and progression of inflammation but could substantially be mitigated by supplementation with antioxidant vitamins C, E and honey.

Pinus massoniana L. was thermally treated with low melting point alloy as heating medium to investigate the strength properties changes. Contact angle, color and scanning electron microscopy were recorded to assess the effectiveness of the treatment. Samples were pre-treated in a micro-wave for 5 min followed by metal bath heat treatment at 150, 180, and 210 °C for 2, 4, and 8 h,respectively. Strength properties of metal bath treated wood were decreased with increase temperature and ***, modulus of rupture, impact bending, modulus of elasticity were reduced for all treatments. Maximum compressive strength slightly increased at 150 °C for 4 h followed by gradual reduction. The Janka hardness was reduced in the tangential and radial directions. Treatment of the wood at 210 °C for 8 h caused the wood to become brittle and rupture. The contact angle was considerably higher after thermal treatment. The color of the wood became darker with increasing temperature of thermal treatment. Micrographs of the heat-treated samples showed damage to the cell wall with increase in temperature. Metal bath heat treatment of wood was carried out successfully and some strength properties were reduced.

Decay resistance and dimensional stability improvement of wood by low melting point alloy heat treatment

引用

Journal of Forestry Research 2018年第6期29卷 1797-1805页

Wood has no inherent natural resistance against agents of biodegradation. We evaluated the effects of metal bath heat treatment(MBHT) on decay resistance and dimensional stability of Chinese parasol(Firmiana simplex) and Chinese fir(Cunninghamia lanceolata) wood. A low melting point alloy was used as heating medium in the treatment of the wood samples at 150, 180, and 210 °C for2, 4, and 8 h. Heat-treated and control samples were exposed to brown rot fungus(Poria placenta) and white rot fungus(Coriolus versicolor) for decay resistance testing and anti-swelling efficiency(ASE). The improved decay resistance with increase temperatures with low mass losses of 7.3 and 7.3% for F. simplex, and 3.9 and 3.6% for *** at 210 °C for 8 h against Coriolus versicolor and Poria placenta, respectively. ASE indicated that MBHT contributed to improved dimensional stability of both wood species after treatment. Scanning electron micrograph results indicate that metal bath-treated samples showed strong decay resistance. Therefore, our approach to thermally modify wood should be explored to overcome the energy utilization by using low melting point alloy for the heat treatment of wood.

Background: Malaria and typhoid have remained major infectious tropical diseases. Clinically, whenever there is severe malaria, cough is always an associating symptom owing to typhoid infection arising from poor hygiene in respect to drinking water and food. There is a strong association between human blood group and disease. Residual malaria transmission, effect of climate change on malaria vector composition, environmental management targeted at malaria breeding control as an intervention strategy are areas of interest to WHO in malaria control in Sub-saharan Africa. A body of data is been built on susceptibility of human blood groups to malaria, HIV and HBV and presently malaria and typhoid. If climate change warrants a change in composition of vectors and as well resistance to ACT therapy, the susceptibility or vulnerability of the human blood group is also called to question. The link between susceptibility of human blood group to malaria and typhoid has not been previously investigated. Purpose: The present study assesses the genetic disposition (susceptibility of human blood groups and abo analysis) to malaria and typhoid infections. Patients and Methods: One hundred (100) patients were screened for malaria and typhoid infections in a tertiary health facility—His glory hospital Lagos, Nigeria. Blood samples were collected by venu-puncture from 53 females and 47 males adults aged between 15 – 47 years, who were infected either singly or coinfected with malaria and typhoid. Microscopic detection of P. falciparum, widal serological technique for salmonella antibody presence and genotypic determination were all done using standard WHO methods. Human material or data were analyzed or performed in accordance with the declaration of Helsinki (2000). Ethical clearance was obtained from the ethic and research committee of the Ministry of Health via the Faculty of the Basic Medical Sciences, University of Calabar (Ethical Certificate number CRS/MOH/HRP/2023/396).
