All stages of Argas persicus were found in crevices in the bark of 49 of 266 trees belonging to 16 species in West Pakistan. These trees had not been used as roosts by domestic birds. The infestation seemed to be restricted to those trees used by vultures (Pseudogyps bengalensis) or herons (Ardea cinerea) for nesting or roosting. Several of the ticks collected contained recently sucked avian blood in the gut but intramuscular injection of crushed material from the ticks into a hen produced no blood infection.Infested trees may be important as sources of the pest near poultry farms and chicken houses.

Ticks transmit a greater variety of pathogenic micro-organisms than any other arthropod vector group, and are among the most important vectors of diseases affecting animals. A survey on the prevalence of tick species infesting domestic birds sold in Gwagwalada main market, Abuja between April and July, 2015. A total of 450 birds were examined by feather separation with fingers and a pair of forceps to expose the skin of the birds for presence of the ticks. An overall prevalence of 25.6% was observed. Out of the 150 domestic fowls examined 62(53.9%) were infested, 44(29.3%) of the 150 Guinea fowl and 9(6.0%) of the 150 Pigeons were infested. Of all the ticks identified, 93(51.4%) were from the Domestic Fowls and 77(42.5%) from the Guinea fowl and 11(6.0%) from Pigeon. Thirty (32.3%) of the ticks from the Domestic fowls were Argas persicus, 25(26.9%) Argas walkerae, 20 (21.5%) Ornithodorus moubata and 18(19.4%) Ornithodorus savignyi. Similarly, 34(44.2%) of the ticks from Guinea fowl were A. walkerae, 20(28.2%) O. moubataand 23(32.4%) O. savignyi. Five (45.5%) of the ticks from Pigeon were A. persicus, 4 (36.4%) were A. walkerae, 2 (18.2%) were O. moubata and no O. savignyi. Observation on the location of tick from the hosts body showed highest prevalence was found under the wings (55.2%) and lowest on the head & neck (5.00%). The result of this research revealed that Gwagwalada market poultry section is endemic of tick infestation. Chemical control with acaricides and improved management and sanitation of the poultry cages in the market should be enforced.

ABSTRACT 1. The metabolism of suspensions of circulating leucocytes has been studied after intramuscular injection of a dose of 50 mg/kg of a corticosteroid (cortisone acetate). The suspensions were incubated under aerobic conditions in the presence of a glucose concentration of 5.6 mm. Glucose consumption, lactate production, and variations in intracellular glycogen concentration were measured. After the administration of the corticosteroid, the anabolic processes of granulocyte metabolism were reversibly stimulated. Glucose consumption and lactate production increased 12 hours after the injection, but tended to normalize after 24 hours. The glycogen content of the granulocytes was enhanced, and glycogen synthesis during the course of the incubation was greatly stimulated. The action of the administered corticosteroid is more prolonged in females than in males. The injection of the corticosteroid caused metabolic modifications which resemble in their modulations and in their chronological development those found in circulating granulocytes of guinea-pigs suffering from sterile peritonitis. These results suggest, therefore, that, in the case of acute inflammation, the glucocorticosteroids may play an important role in the regulation of the metabolism of the blood leucocytes.

ABSTRACT A study was made of the influence of pharmacological amounts of synthetic oxytocin (»Syntocinon«) on the lactating mammary gland of the rabbit. The drug was given by intravenous infusion, by intramuscular injection and by intranasal administration. Two different types of reaction were noted: a tonic reaction, i. e. a lasting increase in pressure in the mammary gland without significant fluctuations, or a rhythmic reaction, i. e. a series of increases in pressure at more or less regular intervals. In order to elicit reactions approximately identical in intensity and character with those produced by intravenous infusion, it was necessary to give approximately 1.5 to 8.0 times as much by intramuscular injection and approximately 10 to 100 times as much by intranasal administration. Intravenous administration of adrenaline transiently suppressed a long-lasting reaction to oxytocin.

The present study aimed to investigate the prophylactic effect of Cymbopogon proximus and Alhagi maurorum on Sulfadimidine induced urolithiasis in rabbits . Thirty New Zealand male rabbits were allocated into six equal groups (each of five): Group (1) was used as a negative control. Group(2) were administered sulfadimidine (200mg/kg) by intramuscular injection.Groups(3) and (4) were administered sulfadimidine(200mg/kg) by intramuscular injection and 330mg/kg of Cymbopogon proximus alcoholic and aqueous extracts respectively orally.Groups(5) and (6) were administered sulfadimidine(200mg/kg) by intramuscular injection and 400mg/kg of Alhagi maurorum alcoholic and aqueous extracts respectively orally. The period of experiment was 10 days. Blood and urine samples were collected from rabbits on the 10th day. The results recorded a significant decrease in serum creatinine, urea, uric acid and crystalluria in Cymbopogon proximus and Alhagi maurorum groups compared to sulfadimidine treated group.We conclude that Cymbopogon proximus and Alhagi maurorum have a nephroprotective and antiurolithiatic effects against sulfadimidine induced crystalluria.
