As is well known, the glomeruli of the frog’s kidney are supplied with blood only by the renal arteries, whereas the renal tubules have a double supply. On the one hand, they receive blood by way of the renal portal veins; on the other hand, the efferent vessels from the glomeruli open into the capillary network round the tubules. The whole of the tubule receives blood from each of these two sources, so that the capillary network around the tubules can be fully injected either from the renal arteries or from the renal portal veins. Taking advantage of this fact it has been shown by Beddard and one of us (F. A. B.) that after complete occlusion of the glomeruli the tubules, when adequately supplied with oxygen, maintain their normal histological appearance, and may secrete urine. In the present experiments an attempt has been made to determine the function of the glomerulus and to ascertain whether the tubules possess the capacity to absorb water and solids.

ABSTRACT Localized hypertrophic neuropathy (LHN) is a disorder of unknown cause that presents with progressive, predominantly motor weakness in the distribution of a single nerve, with the histological appearance of the “onion bulb” formation. Because of its rarity, the condition is often ignored in the differential diagnosis of mononeuropathy. We report a case of LHN involving the posterior tibial nerve and review the literature.

Renal angiomyoadenomatous tumour is a rare, recently describedneoplasm with a distinctive histological appearance. Althoughreported in the pathology literature, to our knowledge, no priorreports have described its imaging appearance. We describe thecomputed tomography and magnetic resonance imaging featuresof an incidentally detected renal angiomyoadenomatous tumourthat appeared as a well-marginated, solid T2-hypointense enhancing mass, in a 50-year-old woman. It is indistinguishable from a variety of benign and malignant renal neoplasms.

✓ The central canal of the spinal cord has been proposed as a significant compensatory alternative pathway of cerebrospinal fluid (CSF) flow in hydrocephalus. Ten dogs were made hydrocephalic by a relatively atraumatic experimental model that simulates the human circumstance of chronic communicating hydrocephalus. The central canal was studied by histopathology and compared with 10 normal control dogs. In both groups the central canal of the spinal cord was normal in size, configuration, and histological appearance. In this experimental model dilatation of the canal and increased movement of CSF does not appear to be a compensatory alternative pathway.

Following limb amputation in the newt (Notophthalmus viridescens), the animals were given daily intraperitoneal injections of 0.1 or 1.0 mg of either indomethacin or acetylsalicylic acid. This had no observable influence on the rate or extent of limb regeneration or the histological appearance of the regenerating limb when compared with controls. Following limb amputation in toads (Bufo americanus), the limb stumps were injected daily for the first 15 days after amputation with 5 μg of either prostaglandin E1 or prostaglandin E2. Neither of these treatments had any observed effect on subsequent wound healing of the limbs when compared with controls. These observations suggest that prostaglandins do not play a major role in control of amphibian limb regeneration.
