    Notes: Abstract Effects of soil amendment with crabshell chitin on the growth of white clover (Trifolium repens L.) and perennial ryegrass (Lolium perenne L.), and on populations of soil bacteria, fungi, and plant-parasitic and free-living nematodes were investigated in a pot trial. Five soil samples were collected from Te Puke (Paengaroa Shallow Sand, a Typic Hapludand) and five from Hamilton (Bruntwood silt loam, an Aquic Hapludand), New Zealand. Subsamples of each soil were either amended with chitin or unamended and planted with white clover and ryegrass. The ryegrass shoot weight in amended soil was greater (P〈0.01), most probably due to N mineralised from chitin. A significantly lower (P〈0.01) root: shoot ratio of ryegrass in the amended soil also suggested improved N availability, and therefore less root mass was needed to support a given shoot mass. A reduction in nodulation was observed in 12-day-old white clover seedlings (P〈0.05) and also in 6-week-old seedlings (P〈0.01). The shoot weight of white clover was significantly lower (P〈0.05) in amended soil, possibly due to phytotoxic effects of chitin. Chitin increased (P〈0.01) the populations of bacteria and fungi by 13-fold and 2.5-fold, respectively. The cyst nematode of white clover, Heterodera trifolii, was significantly reduced in chitin-amended soil, possibly due to increased levels of chitinase produced by rhizosphere microorganisms. Two other plant-parasitic nematodes, Pratylenchus spp. and Tylenchus spp., were also reduced in ryegrass roots and in soil as a result of the chitin amendment. However, the total number of free-living nematodes increased 5.4-fold in amended soil.

    Notes: Summary The pathways and terminal projections of the inferior olivary complex and the lateral reticular nucleus (LRN) to the cerebellar nuclei and cortex in the rat were studied using unilateral and bilateral injections of 35S-methionine followed by light microscope autoradiography. The cerebellar projections from unilateral olivary injections show heavy contralateral, crossed and light, ipsilateral, uncrossed projections in sagittal bands in the deep nuclei and in the molecular layer. The crossed projections occupy all cortical lobules. Bilateral olivary injections that encompassed all subdivisions of the nuclear complex on both sides demonstrated that the same pattern of sagittal zonation is preserved although in this case distributed bilaterally. Thus, the representations of ipsilateral and contralateral projections of both sides overlap precisely and banding is preserved. These data suggest that the olivocerebellar climbing fibers occupy the banded areas and that the empty strips of molecular layer between them must have climbing fibers of extra-olivary origin. It was also found that climbing fiber rosettes are present in the granular layer borne by collaterals of axons en route to the molecular layer; their distribution is not restricted to the molecular layer bands. Unilateral injections in the LRN produced heavy, uncrossed, ipsilateral and light, crossed, contralateral projections with the crossing occurring in the cerebellum. Projections to the deep nuclei occur and the terminal arborizations in the cortex are dense fields of mossy fiber rosettes forming narrow sagittal bands restricted to the granular layer. These mossy fiber rosettes contrast sharply in their number and distribution to the climbing fiber rosettes. The data from these studies strengthen the evidence gathered from morphological and physiological studies that the entire cerebellum may be organized on a plan involving narrow sagittal strips with structural, functional and chemical significance.

    Notes: Summary Four monoclonal antibodies specific for somatostatin have been produced and characterized. These antibodies were used to assess the anatomical relationship of somatostatin-containing cells in the pancreas and gastrointestinal tract of man, baboon and rat with ten other peptide-containing endocrine cells. The peptides investigated were gastrin, cholecystokinin, motilin, secretin, neurotensin, gastric inhibitory polypeptide, gut-glucagon, pancreatic glucagon, pancreatic polypeptide and insulin. The only regions in which somatostatin cells were seen in close contact with another endocrine cell were in the pancreas and the gastric antrum. In the pancreas somatostatin cells were commonly seen in close contact with insulin, glucagon and pancreatic polypeptide cells and infrequent contact was demonstrable with the gastrin-immunoreactive cells in the antrum of both rat and man. In all other cases no evidence was obtained for a close anatomical relationship between somatostatin cells and the other enteroendocrine cells.

    Notes: Summary Calcitonin gene-related peptide-like immunoreactivity was demonstrated in in sensory nerve fibers in the epidermis and dermis as free nerve endings and around blood vessels and hair follicles of the human finger pad and arm skin. The vast majority of the calcitonin generelated immunoreactive fibers was shown to display also substance P-like immunoreactivity and a few fibers in the dermis were somatostatin positive. No fibers displaying both substance P and somatostatin-like immunoreactivity were found but a few substance P immunoreactive fibers in the dermis-epidermis region were found to contain also vasointestinal polypeptide-like immunoreactivity. In the sweat glands, abundant calcitonin gene-related peptide positive, but substance P negative, fibers were observed with a similar distribution pattern as the vasoactive intestinal polypeptide immunoreactive fibers and these fibers were suggested to be of sympathetic origin.

    Notes: Summary A starch gel electrophoretic procedure is described that resolves peptidase S (PEPS) as well as the peptidases A, B, and C in man-rodent, rodent-rodent, and primate-rodent interspecific somatic cell hybrids. The interspecific PEPS cell hybrid phenotype can be resolved into a pattern which suggests that PEPS is composed of five or six identical subunits. Results are presented supporting assignment of the PEPS locus to chromosome 4 in man using man-mouse and man-Chinese hamster somatic cell hybrids. Human genes coding for peptidases A, B, C, and D were assigned to chromosome 18, 12, 1, and 19, respectively, confirming previous assignments. These somatic cell genetic data demonstrate the independent genetic control of the several human peptidases.

    Notes: Summary A monoclonal antibody raised to gastric inhibitory polypeptide (GIP) has been compared with conventional rabbit and guinea-pig antisera to GIP. Four staining methods were tested and of these the peroxidase antiperoxidase (PAP) method proved to give the best results with both the mouse and rabbit antibodies. The monoclonal antibody, when used to stain pancreatic tissue, gave negative results whereas a distinct population of gut endocrine cells was readily demonstrable, suggesting that GIP is not a constituent of the mammalian pancreas. The monoclonal antibody was found to be the most sensitive for immunocytochemistry achieving the titre of 1:106 in rat gut. A C-terminal specific antibody, with a high affinity and avidity to GIP, it was clearly the preferred antibody for immunocytochemical studies.

    Notes: Abstract The two-dimensional thermal problem due to relative motion of a medium and a suddenly activated circular heat source is solved for several boundary conditions. The solutions can be interpreted as for a moving heat source in a stationary medium or a medium moving past a stationary heat source. Uniform and non-uniform temperature, and uniform and non-uniform heat flux boundary conditions are considered. The effect of velocity and radial direction on the temperature distribution is examined. Average, steady-state Nusselt numbers are derived. The transient response of a continuous line source is obtained as a limiting case of the prescribed heat flux solution.

    Notes: Summary The polypeptide hormone GIP has been localized ultrastructurally by using specific, monoclonal GIP antibodies and an immunogold technique on aldehyde-osmium fixed specimens of dog duodenal mucosa. A single type of cell showing round, homogeneous, fairly osmiophilic granules with closely applied membrane and a mean size of 188 nm±34 SD has been identified as the GIP cell.
