ANATOMICAL DISPOSITION OF CARPAL BONES OF GOLDEN RETRIEVER DOG BY X-RAY EXPOSURE

The present study was conducted to know the general disposition of bones in carpal region of experimental dogs by X-ray study with an objective that the findings will facilitate to have an in-depth knowledge about the proper positioning of the carpal bones for surgical management of fractures and different types of bone deformities in dogs. In the present study, the anatomical disposition and arrangement pattern of carpal bones playing a pivotal role in providing the structural conformity in the limbs of Golden Retriever dog has been thoroughly confirmed by Xray exposure

HOUSE DUST MITES IN RELATION TO DIFFERENT HABITAT CONDITIONS OF KOLKATA METROPOLIS, INDIA

House dust mites play an important role in the pathogenesis of allergic diseases. Both the common species of the genus Dermatophagoides viz. Dermatophagoides pteronyssinus and D. farinae and other two allergenic species Blomia tropicalis and Austroglycyphagus geniculatus are found to be abundant in the dust samples collected from beds of patients suffering from nasobronchial allergic disorders residing at Kolkata metropolitan areas. The presence of these four mites in large quantity in the patients environment are clinically correlated with the aetiopathology of various allergic manifestations like allergic rhinitis, bronchial asthma etc. House dust mites usually occupy different niches in the homes of asthmatics and are significantly higher in beds than else where in the house. However, the distribution and abundance of these mites are influenced by several microclimatic conditions. The aim and objective of the present study is to assess the impact of different microclimatic conditions like type of houses, type of mattresses and bed and floors of the room on the distribution and abundance of house dust mite population. In view to provide the patients with best possible diagnosis and treatment, proper identification of offending allergens and their subsequent reduction from the patient’s environment is of outmost importance which in turn may be helpful for the prophylactic management of these dreadful diseases in Kolkata metropolis

LIFE-CYCLE OF HOUSE DUST MITE DERMATOPHAGOIDES PTERONYSSINUS (ACARI: PYROGYLPHIDAE) UNDER LABORATORY CONDITIONS IN KOLKATA METROPOLIS

The life cycle of Dermatophagoides pteronyssinus was studied at 25 OC and 80% relative humidity. Observation was made on freshly laid eggs until they develop into adults and periods between different stages were recorded. The eggs required an average 11.26 days to develop into adults. The ranges of life longevity of mated males and females were 18–64 days and 20–54 days, respectively. The conditions used in the rearing experiments may be considered optimal for maintaining culture of D. pteronyssinus
