It has been shown that desensitization of the responses of vascular smooth muscle could occur if the physiological saline composition is altered. The extent to which Bay K 8644 and nifedipine affect the calcium responses of a vascular
smooth muscle and their effects on desensitized tissue responses are yet to be quantified and this is what this study aims at doing on calcium-mediated responses in the rat tail artery and on the desensitization of the responses of the

The effect of different forms of and mode of application of chicken manure on the growth rate of Oreochromis niloticus was compared. The forms and modes included Wet Chicken Manure broadcasted into culture water, wet Chicken Manure tied in jute bags and dry Chicken Manure broadcasted into pond. The culture was carried out in 25 litres plastic bowls for a period of 10 weeks.

Clariid catfish hybrid (Clarias gariepinus x Heterobranchus bidorsalis) fingerlings were reared in outdoor concrete tanks for a 24-week experiment period. The concrete tanks measured 2.24 x 1.79 x 0.96m and were filled with water to a depth of 0.77m.The study was conducted using four tanks in a completely randomized design with treatment (feeding frequency) replicated twice.

The effects of a low carbohydrate high fat Nigerian like diet on lipoprotein levels, serum electrolytes, liver and renal functions were investigated. The diet consist of 28% carbohydrate and 35% fat as percentage of total energy in a wholly compounded form. Twelve rabbits were randomly divided into two groups. The groups were: Group I that was fed the control diet and the second group II were fed with the low carbohydrate high fat diet. At the end of eight weeks, biochemical analyses were done on blood samples of the animals.

The general procedure for maintaining isolated tissues in vitro is to equilibrate at atmospheric pressure, with a gas mixture of high oxygen content, such as 100% or where CO2 / bicarbonate buffering is used, 95% O2 is employed. But in a classical resistance vessel, such as the rat tail artery, little attention has been paid to the difference between normoxia of 16% and hyperoxia of 90% O2 .

Background: The size of the newborn at birth is affected by maternal nutrition. It is therefore conceivable that birth weight would also be influenced by maternal anthropometry which in turn, is often influenced by maternal nutrition and socio-economic factors. In this study, the effects of maternal anthropometry and socio-demographic factors on the newborn weight, length, and occipito-frontal circumference (OFC), were evaluated.

Fry of hybrid clariid catfishes, Clarias gariepinus x Heterobranchus bidorsalis, were reared at four densities in indoor aquaria to evaluate the effects of stocking density on survival, growth and feed utilization. Fish (mean weight 0.84g) were stocked into 41-L aquaria containing 12L of water at rates of 11, 22, 33, and 44 fish per aquarium (978, 1956, 2933 and 3911 fish/m3) respectively. Each treatment was replicated three times.

Sweat rate and sweat electrolyte loss were studied in 32 male Nigerians. Each subject was studied thrice at room temperature (RT) of 270C+20C and a relative humidity (RH) of 70+5%; at 370C and RH 90+5%; and during exercise at
RT0C+20C and RH 70 %. Sweat was collected simultaneously from the forehead and forearm using the filter paper disc technique.

Earlier studies have shown that alkaline injuries are especially damaging to the corneal structure with corneal ulcerations as comnon occurrence after significant alkali burns, and this is due to collagenolytic enzymes (collagenase) secreted by the cornea in response to the presence of the chemical; causing collagen loss. This has necessitated treatment using ascorbic acid, a collagenase inhibitor. 20 male and female rabbits (1.0-2.5kg body weight) were randomly divided into 2 groups of 10 each.

The traditional staged operation for acute sigmoid volvulus is giving way to one stage resection. Similarly, the conventional requirement for bowel cleansing is being increasingly questioned. In this report, we reviewed the outcome of our management over a ten-year period. There were 24 patients aged 23-100 years. Of these, 21 had one-stage primary resection with no clinical anastomotic leak and only one wound infection and fascial dehiscence.

A survey of 1431 gram-negative bacilli from June 2001 to September 2005 were obtained from the faeces of 920 HIV/AIDS patients attending some Clinics and Hospitals in Benin City, Nigeria, were screened for quinolones resistance gene. The HIV/AIDS patients CD4 cells range was 14/mm3 800/mm3 of blood. Out of the 1431 isolates, 343 (23.9%) were resistant to quinolones with a MIC for nalidixic acid.

Copy manufacture and substitution approach were employed to manufacture the critical parts of a 3hp petrol engine. The produced spare parts were tested individually and collectively. The engine performed well with the use of the
manufactured spare parts. However, slightly lower engine speeds and higher engine temperatures were obtained when the spare parts were used.

This study investigated the effect of study technique in enhancing effective learning among primary schools pupils. 154 pupils constituted the sample size. They were exposed to treatments in two fixed levels. One of the groups was exposed to Survey Questions Reading Recall and Review (SQ3R) study technique proposed by Robinson (1946) while the other group was exposed to a non-specific treatment. The design is a 2 x 2 factorial
consisting of treatment/control groups and boys/girls groups..

The decision to remove an eyeball is usually a difficult one for both the surgeon and patient. From the surgeon’s position, it is an acceptance of total defeat at any efforts that may have been able to salvage the vision or the eyeball. For the patient, the loss is enormous since any form of artificial replacement of the organ is usually functionless, (vision wise). At best an improved cosmetic appearance is all that is achieved. This study highlights those factors that cumulate in the removal of the eyeball either by enucleation or by evisceration.

Cultural taboos and their sanctions have helped to check abuse of the environment at least among the local people. The disregard for these traditional checks and balances especially among Christians has adversely affected their enforcement at this time. The environment and culture preservation in Awka-South were investigated. The faithful observance of the traditional laws in the study area was attributed to the fact that Awka-
South area had remained occupied by the same people for centuries.
