“…Renyi-Vamos et al (49) reported that a suspension of live pathogenic bacteria (Escherichia coli) or of Streptococcus toxin in the ureter which was then ligated, generally produced cortical ischemia bilaterally and that the ischemia could be reduced by renal denervation. Richards (50) and Bieter (3,4,5) found that stimulation of the splanchnic nerves diminishes the number of active glomeruli in the frog's kidney and that the reverse occurred. when the kidney was denervated.…”

“…Farrell (28) observed that distension of the bladder or renal pelvis or stimulation of a pelvic nerve in the dog depresses renal volume and that this is prevented by division of the pelvic nerves. Richards (50) and Bieter (4,5) noted reduction in the number of active glomeruli in the frog upon stimulation of the sciatic nerve. Franklin (30) discovered that distending the uterus of the rabbit results in renal cortical ischemia, which effect is prevented by denervating the kidney.…”

Effect of Electrical Stimulation of Medial Popliteal Nerve On Caliber of Renal Arteries in Unanesthetized Man

Since the studies of Bywaters et al. (12)(13)(14)(15)(16)(17) upon renal failure in man following prolonged crush of the thigh(s), interest has been shown in stimulation of the sciatic nerve of animals with the view that this excitation may be contributory to renal shutdown of the &dquo;crush syndrome&dquo;. We undertook stimulation of a major branch of the sciatic in unanesthetized cooperative human subjects, most of whom had normal or near-normal kidneys. This was done in the course of translumbar aortography (renal arteriography) which supplemented the usual diagnostic armamentarium partly because most of the cases had &dquo;idiopathic&dquo; gross hematuria and we were doing our utmost to rule in or out renal neoplasm (cf. Maluf (42)) for validity of this concept. TECHNIQUEOur method of translumbar aortography in unanesthetized patients has been described elsewhere (42). The cathode-tube was centered directly over the expected site of origin of the renal arteries from the aorta, i.e. at Ll/L~. The kidneys thus appear about the middle of the film. In the present study special care was taken to infiltrate only the skin and subcutaneous tissue with the analgesic, 0.5 per cent procaine HCI. After considerable experience with translumbar aortography it has become possible to enter the aorta painlessly with local anesthesia applied only thus. The exposure-time for obtaining each radiogram was 0.25 sec.The patient was given 200 mg. of sodium luminal subcutaneously as a mild hypnotic half an hour before the first aortogram. Five to 10 minutes before the first aortogram meperidine HCI, 100 mg., was administered intravenously as a general analgesic. The first aortogram was obtained by injection of 35 cc. of 70 per cent Urokon (Na 3-acetylamino-2 , 4 , 6-tri-iodobenzoate) in about three seconds, or as rapidly as possible. The needle was then withdrawn about 3 cm. and its obturator completely re-inserted. The patient was requested not to move in the slightest from his position. He was warned of every step about to be taken and of what he probably would feel, thus preventing alarm and movement on his part. The left or right medial popliteal (posterior tibial) nerve was then stimulated percutaneously in the popliteal fossa for thirty minutes. The electrical stimulator, thyratron-type, was obtained by the courtesy of L. A. Geddes, from the

“…Our in vivo studies of adult renal allografts allowed direct study of the functioning glomerulus. Other in vivo studies are scarce and limited generally to amphibia (59) with the exception of Greenblatt and others (6) and Baringer (60). The majority have based their opinions on injection techniques (57,61) and more indirect studies (62,63).…”

Early experiments using in vivo microscopy on mammalian tissues were reviewed by Clark et al. (1). The introduction of the transparent rabbit ear chamber, first described by Sandison (2, 3) has allowed microscopic observations to be made of the structure and function of a thin layer of living tissue in the mammal for periods up to several years (4).A modification of the Sandison-Clark rabbit ear chamber which allowed the mica cover slip to be removed, exposing the surface of the stable vascular membrane and then replaced, was adapted by Williams (4) to study graft tissue fragments implanted on the membrane. He found that autografts of a wide variety of tissues in fragments less than 1 mm diameter became vascularized by the anastomosis of graft vessels to the chamber vessels immediately beneath, and slowly became incorporated into the membrane. These grafts retained their structure and visible function (5). On the other hand, allograft tissues, with the exceptions of choroid plexus, ciliary body, V2 carcinoma, and to some extent adrenal, did not survive (5).Recently Greenblatt and others (6) established renal allografts in the hamster cheek pouch chamber and described the glomerular blood flow occurring during their brief survival. However, only fetal graft tissues could be used successfully and the glomerular blood flow always followed a preferential path in a relatively direct stream from the afferent to the efferent arterioles. Subsequently he has described fetal and neonatal heart grafts functioning in these chambers (7).With the eventual aim of studying the process of allograft rejection in vivo, we implanted tissues into the rabbit ear chamber b y a method adapted by Cliff et al. (8). Tissues successfully grafted include liver, kidney, myometrium, and thyroid. Materials and MethodsAnimal.--Rabbits used as recipients were obtained from a closed colony of half-lop rabbits maintained at the Australian National University. They were hardy animals with durable half-lop ears 16 cm in length, very suitable for transparent chamber insertion. Donor rabbits were either of a similar strain, though unrelated, or of an albino strain. Animals were fed on * Present address:
