In this study, 10 Hasak sheep lungs from Konya Bahri Dağdaş International Agricultural Research Institute, Unit of Experimental Animals Unit were used. Corrosion casting technique were applied to the materials. The corrosion cured materials were stored in water for one night. It was then incubated at 37 ° C in a 20% KOH solution for 24 hours. Corrosion casting technique and latex injection materials were photographed and presented in the study. The lungs were found to be wrapped with pleura visceralis (pleura pulmonalis) in the cavum thoracis. It was determined that the right lung was consisted of lobe cranialis (pars cranialis and pars caudalis), lobus medius, lobus caudalis and lobus accessorius. The left lung was composed of lobe cranialis (pars cranialis and pars caudalis) and lobe caudal. In the bronchus that shaped these lobes, it was determined that tacheae gave bronchus lobaris cranialis dexter (bronchus trachealis) mean 48.53 mm before the bifurcatio trachea, and later on it was divided into bronchus pirincipalis dexter and sinister. In this study, anatomical features of broncho-pulmonary segmentation and similarities and differences with other species were revealed.

In this study a physical, chemical and physiological characterization of Dominico Hartón plantain grown in the Belalcázar municipality (Department of Caldas, Colombia) during harvest and post-harvest was carried out. The research was performed with fruits of 14, 16 and 18 weeks after flowering. Every two days until senescence changes in weight, firmness, parameters of color L*a*b*, pulp/peel, the relationship pulp/shell, maturity index, pH, humidity, starch, respiration rate and ethylene rate were measured. This study used a longitudinal repeated measures design, balanced, with a three-level factor. The factor evaluated was harvest time and the response variables were the physicochemical parameters. The results showed variation in weight near to 7%, the color parameter tint was between -61.46 and 86.74, chroma between 26.31 and 37.11 and DE of 1.4603 to 8360, the pH ranged from 6.2 to 3.98, pulp/peel of 2.53 to 4.11, the relationship °Brix/acidity of 11.36 to 26.2, humidity content between 60.56% and 56%, starch, 51.7% to 67% DM, the CO2 production rate between 3.4 and 8.9 g / kg. h, ethylene from 24 to 225 µL / kg. h. The maturation parameters showed climacteric behavior and total days of ripening were 9, 14 and 21 for the fruits of 18, 16 and 14 weeks from flowering. | En el departamento de Caldas, Colombia, se realizó la caracterización física, química y fisiológica durante las fases de cosecha y poscosecha del plátano Dominico Hartón (Musa AAB Simmonds) cultivado en el municipio de Belalcázar. La investigación se hizo con frutos de 14, 16 y 18 semanas después de la floración. Cada 2 días y hasta senescencia se evaluaron los cambios de peso, firmeza, parámetros de color L*a*b*, relación pulpa/cáscara, índice de madurez, pH, humedad, almidones, índice de respiración y tasa de etileno. En este trabajo se utilizó un diseño longitudinal de medidas repetidas, balanceado, con un factor en tres niveles. El factor evaluado fue el tiempo de cosecha y las variables de respuesta fueron los parámetros fisicoquímicos. Los resultados mostraron variación en peso cercanas a 7%, el parámetro de color tinte varió entre -61.46 y 86.74, el croma entre 26.31 y 37.11 y el DE entre 1.4603 y 8.360, el pH varió entre 6.2 y 3.98, una relación pulpa/cáscara entre 2.53 y 4.11, la relación °brix/ acidez entre 11.36 y 26.2, la humedad entre 60.56% y 56%, el almidón entre 51.7% y 67% de MS, la tasa de producción de CO2 entre 3.4 y 8.9 g/kg por hora, el etileno entre 24 y 225 µlt/kg por hora. Los parámetros de maduración mostraron comportamiento climatérico y los días a maduración total fueron de 9, 14 y 21 para los frutos de 18, 16 y 14 semanas desde floración.

Sıçanlarda paklitaksel (PTX) kaynaklı akciğer hasarına karşı misoprostol’ün (MP) koruyucu etkilerinin incelendiği bu çalışmada, yirmi bir adet dişi Sprague-Dawley cinsi sıçan kullanıldı. Bu hayvanlardan rastgele bir seçimle Kontrol, PTX ve PTX + MP olmak üzere 3 grup (n=7) oluşturuldu. Kontrol grubuna 1 mL %0,9 NaCl intraperitoneal (i.p.) ve 1 mL %0,9 NaCl oral yolla 6 gün boyunca verildi. PTX ve PTX + MP gruplarına çalışmanın 0., 2., 4. ve 6. günlerinde her sıçana 2 mg/kg PTX i.p. olarak verildi. PTX + MP grubuna ayrıca 6 gün süreyle 0,2 mg/kg/gün MP oral olarak verildi. Doku numuneleri sıçanlardan anestezi altında alındıktan sonra bu numunelerde biyokimyasal ve histopatolojik analizler yapıldı. Yapılan analizlerde PTX grubu sıçanlarda akciğer dokusundaki süperoksit dismutaz (SOD) ve katalaz (CAT) aktiviteleri ile glutatyon (GSH) düzeyinin azaldığı, malondialdehit (MDA) düzeyinin ise yükseldiği belirlendi. Yapılan histopatolojik incelemelerde ise, PTX grubu sıçanlarda alveol yapısında düzensizlik ve kalınlaşma, perivasküler ödem ve perivasküler alanda inflamatuar hücre infiltrasyonu gibi histopatolojik değişikliklerin şekillendiği tespit edildi. PTX + MP grubunda ise, PTX grubunda tespit edilen patolojik değişikliklerin büyük oranda önlendiği görüldü. Elde edilen bu sonuçlar; PTX’in neden olduğu akciğer hasarının önlenmesinde MP’nin etkili olduğunu göstermekte olup, kanser tedavisinde bu iki ilacın birlikte kullanılmasının faydalı olacağını düşündürmektedir.
