🔖Definiation of glomerulonephritis? 👨🏻‍⚕️immunological inflammation injury of glomeruli,mediated by hypersensitivity reaction type 3 🔖Two types of glomerulonephritis: 1-primary glomerlonephritis 2-secondary glomerulonephritis 🔖Primary glomerulonephritis:involved the kidney ,not associated with other organ diseases, it inculde the following: 1-Acute post infectioous glomerulonephritis 2-Rapidlly progressive glomerulonephritis 3-Minimal change disease 4-Focal segmental glomerulosclerosis 5-Membranous glomerulonephritis 6-Membranoproliferative glomerulonephritis The detalis of each one look to picture below👇🏻 #Renal_pathology #H_S

تعديل Candle jar is used to get anaerobic

🔹Container ...used for sample collection as urin and stool . 🔹API(analytical profile index )...for isolation and identification of bacteria . 🔹Wire loop /needle ...used for routine inoculation of agar slope deep and making streak plate. 🔹Calibrated loop ...for inoculation of urin sample . 🔹Bunsen Burner ...used for sterilization of wire loop and metal forceps . 🔹Counter plate ...for counting bacteria . 🔹Balance ...used for weighting the culture media . 🔹 Centrefuge ....for centrifuge sediment particles (cells,bacteria,parasites ) suspended in fluids /used for separated of samples (blood ,urin ,body fluids) 🔹Candle jar ...to get aerobic and microaerophilic atmosphere. 🔹Autoclaves ...used for sterilization device depend on moist heat ,used for sterilization of culture media and contaminated materials. At 121c for 15 minutes under high pressure 16 psi /1.2 Pascal وهذا يستخدم في تعقيم الابكوت وملابس العمليات . 🔹Hot air oven ....used for sterilization of glass petri dishes ,pipettes and rubbers. depends on moist heat ,sterilized by dry heat .
