ABSTRACT

AIM: To investigate the effects of selective phosphodiesterase 3 inhibitor olprinone on cough response in guinea pigs sensitized and challenged with ovalbumin. METHODS: Forty sensitized guinea pigs were randomly divided into control ( n = 10), challenged ( n = 10), olprinone ( n = 10) and aminophylline group ( n = 10 ). Two hours after challenged with the aerosol of 1% ovalbumin or saline, animals were intraperitoneally injected either with saline,25 mg/kg of olprinone or 25 mg/kg aminophylline. At 24 h, the injection was repeated with 2. 5 mg/kg and 25 mg/kg olprinone or 2. 5 mg/kg and 25 mg/kg aminophylline respectively in olprinone and aminophylline group, cough response to inhaled capsaicin and airway responsiveness to methacholine (PC150) were measured. Then, total cell number and differential counts were analyzed in bronchoalveolar lavage fluid. RESULTS: The cough frequency was (5 ± 2) times/3 min in control group and (24 ± 3 ) times/3 min in challenged group ( P < 0. 05 ), while PC150 was (659 + 57 ) mg/L in control group and (238 + 67 ) mg/L inchallenged group ( P < 0. 05 ). 25 mg/kg olprinone significantly inhibited the augmented cough response and airway hyperresponsiveness, the cough frequency and PC150 were (15 ±2) times/3 min and (580 ±45) mg/L (P < 0. 05 ), which differed significantly from (18 ± 2) times/3 min and (438± 52) mg/L in aminophilline group (P < 0. 05). However, olprinone failed to reverse the elevated total cell number and percentage of eosinophils in bronchoalveolar lavage fluid from guinea pigs challenged with ovalbumin (P > 0. 05 ). CONCLUSION: Phosphodiesterase 3 inhibitor attenuates cough response associated with eosinophilic airway inflammation by bronchodilatory effect.

ABSTRACT

This paper presents the results of the gross dissection and the histologic observation on the thyroid and parathyroid glands of Rhinopithecus. Specimens used in the studies are composed of R. roxellanae (1 (?), subad.), R. bieti (2 ♀♀, ad.; 1 ♀,juv.) and R. brelichi(2(?)(?),ad.). Besides the position and shape of the gross anatomy of the thyroid and parathyroid glands, attention was paid to the cellular types of the parathyroid glands. Material used for the histologic investigation is stained with HE and the modified Mallory-Azan methods and observed under the light microscopy. The principal results are summarized as follows:1. The thyroid gland consists of two lateral obes. The dimension of the gland measured 18.0?9.0, 15.0?8.0 and 14.0?6.0 mm. in bieti;23.0?9.0 mm. in roxellanae; 25.0?9.0 and 30.0?1.0 mm in brelichi; and one isthmus measures 3.0?10.0, 2.0?10.0 and 2.0?6.0 mm. in bieti; 4.0?6.0 mm. in roxellanae; 5.0?12.0 and 5.0?14.0 mm. in brelichi.The total weight of the gland is 1.0, 0.5 and 0.3g in bieti; 0.9g in roxellanae; 0.9 and 1.8g in brelichi.The isthmus connects the lower edges of two lateral lobes. There is no pyramidal lobe.2. The blood supply is derived from the superior thyroid arteries. There are no inferior thyroid arteries in three kinds. The thyroid venous drainage is by the superior and inferior thyroid veins, there is no median thyroid vein.3. The sizes and shapes of the thyroid vary with species. Each animal possesses two parathyroid glands, one of each side, but their position is also variable in the different animals.4. The follicular epithelium of the thyroid contains two cellular types, viz. the typical follicular epithelial cells and C cells.5. The parathyroid gland of Rhinopithecus is histologically similar to that of Macaca mulatta and man, which contains four basic cellular elements. There is an intermediary cellular type probably a variant of the oxyphil cells.6. Grey blue granules are present in the pale oxyphil cells of the parathyroid glands of both brelichi and bieti.7. There are less oxyphil cells among the parenchymal cells of the parathyroid gland in the subadult roxellanae than in both bieti and brelichi.
