Penelitian ini bertujuan untuk mengetahui perbedaan biometri dan morfometri spermatozoa kambing Kacang, Peranakan Ettawa dan Boer. Penampungan semen dilakukan menggunakan vagina buatan. Satu bagian semen segar diencerkan dengan sepuluh bagian NaCl fisilogis (v/v). Fiksasi slide dengan cara mencampur satu tetes semen encer dengan satu tetes larutan Eosin-nigrosin, homogenkan dan keringkan diatas hot plate suhu 40°C selama beberapa menit. Biometri dan Morfometri spermatozoa diukur dengan mikroskop phase contras (CarlZeis, Jerman) pembesaran 400 kali. Semen dari setiap kambing dibuatkan satu slide dan setiap slide diambil 10 sampel spermatozoa hidup, sehingga sampel spermatozo untuk setiap jenis kambing adalah 50 spermatozoa. Signifikansi antar variabel diuji menggunakan T-test dengan pengujian independent samples test dengan tingkat signifikansi 0.05. Hasil penelitiann menunjukkan, tidak ada perbedaan nyata variabel biometri ketiga jenis kambing tersebut, kecuali konsentrasi, motilitas massa dan motilitas individu spermatozoa kambing PE secara signifikan lebih rendah dibanding kambing Boer dan Kacang. Panjang kepala spermatozoa kambing kacang, Ettawah dan Boer, tidak berbeda nyata. Sebaliknya, lebar kepala spermatozoa kambing Boer cendrung lebih lebar tetapi tidak berbeda nyata dibanding kambing Kacang dan kambing PE. Sedangkan panjang ekor spermatozoa kambing Boer secara signifikan lebih pendek dibanding kambing Kacang dan kambing PE. Disimpulkan, Morfomerti spermatozoa kambing Kacang PE dan Boer tidak berbeda nyata. Disarankan supaya hasilnya lebih akurat, pengukuran morfomerti spermatozoa hendaknya dilakukan pada spermatozoa dengan kromosom yang sama yaitu X atau Y saja

Although erythrophagocytosis by various species of Entamoeba is a well known phenomenon this has not yet been studied in detail at the ultrastructural level. The present work deals with the description of the incorporation process of erythrocytes by trophozoites of E. histolytica. For this study, trophozoites of E. histolytica, HK-9:NIH strain cultured in axenic conditions and washed human erythrocytes were placed on a hot plate at 37°C in physiological saline solution. After 5 minutes, 2.5% glutarldehyde was added and the samples were processed according to conventional techniques for electron microscopy.Based upon light microscopy studies on living trophozoites in contact with erythrocytes, it seems that erythrophagocytosis only takes place in one pole of the parasite.

Immunoelectron microscopy of neoplastic lymphoma cells is valuable for precise localization of surface antigens and identification of cell types. We have developed a new approach in which the immunohistochemical staining can be evaluated prior to embedding for EM and desired area subsequently selected for ultrathin sectioning.A freshly prepared lymphoma cell suspension is spun onto polylysine hydrobromide- coated glass slides by cytocentrifugation and immediately fixed without air drying in polylysine paraformaldehyde (PLP) fixative. After rinsing in PBS, slides are stained by a 3-step immunoperoxidase method. Cell monolayer is then fixed in buffered 3% glutaraldehyde prior to DAB reaction. After the DAB reaction step, wet monolayers can be examined under LM for presence of brown reaction product and selected monolayers then processed by routine methods for EM and embedded with the Chien Re-embedding Mold. After the polymerization, the epoxy blocks are easily separated from the glass slides by heatingon a 100°C hot plate for 20 seconds.
