1. Introduction A common objective of sanctuary or unfished zones in marine protected areas MPAs ; is to help maintain viable fisheries in adjacent areas by reducing collapses of fish stocks, increasing the density and sizes of fish, and providing centres for dispersal of individuals and larvae Kelleher, 1999 ; . Many studies have demonstrated a recovery of fish populations after sanctuary no-fishing ; zones have been declared Roberts, 1995; McClanahan and Kaunda Arara, 1996; Russ and Alcala, 1996; Wantiez et al., 1997 ; and fished and unfished areas have been shown to differ in abundance, biomass, and numbers of species of fish Watson and Ormond, 1994; Rakitin and Kramer, 1996; Roberts and Hawkins, 1997; Babcock et al., 1999; McClanahan et al., 1999; Chiappone et al., 2000 ; . Differences have, however, usually been detected when fishing included: a number of methods such as spears, nets, traps, and lines that may affect a range of species; intense fishing pressure; little or no regulation; or pressure exerted by commercial or artisanal fishers. Fewer studies have compared fished and unfished coral reef areas where there are only recreational line fishers. Line fishing may have a different effect because it is selective for particular species, less intensive than netting or trapping, influenced by the abilities of the fisher, and controlled by recreational desire rather than economic necessity. Differences between areas may be smaller where line fishing is the major method. We wanted to test whether there were differences in the populations of targeted fish between sanctuary and fished areas where: size and bag limits were applied, regulatory compliance was high, and fishing pressure was exerted by recreational line fishers only. A further aim was to test whether sanctuary areas preserved or enhanced the biomass of mature-sized fish. A suitable location for the study was Ningaloo Marine Park in Western Australia. This region had areas closed to fishing sanctuary zones ; , minimum size and bag limits for predatory fish, and fishers appeared to comply with regulations. Beach netting and spearing were permitted in some small designated areas, but were generally not allowed. Recreational fishing, but not commercial fishing, was permitted in recreation zones. Hence, fishing pressure was only exerted by recreational line fishers. Fishing pressure along the reef varied CALM, 1999; Sumner et al., 2002 ; due to variable access. In some locations, the coral reef is only tens of metres from shore, making it highly accessible to fishers and tourists. Under these circumstances, it was possible to compare fished and unfished areas where differences may be restricted to larger legal-sized predators that could be captured by line. The marine park was established in 1989 and sanctuary zones were implemented in 1991. Anecdotal evidence indicated that the region was heavily fished prior to this time Weaver, 1998 ; . There was.

Early investigations Theiler et al., '15; Bechdel et al., '26, '27, '28 ; dealing with the vitamin B requirements of ruminants were handicapped by the existing lack of knowledge regard ing the complex nature of the B vitamins and by the lack of well-defined methods of assay. Reinvestigation of the problem in the light of more recent knowledge is therefore timely. It was previously reported McElroy and Goss, '39 ; that thiamin was synthesized in the rumen of sheep. The animals were fed a ration deficient in thiamin and their rumen and reticulum contents were found to contain more than 5 pg. of thiamin per gram. Additional assays have been made to determine more accurately the thiamin potency of this sheep rumen and reticulum material and also to determine if a similar synthesis of thiamin occurs in the rumen of the cow.

In addition two smaller scale anti-EGFR affinity chromatography experiments also were performed where the monoclonal antibody EGFR.1 ; , recognizing an extracellular domain EGF receptor epitope, was used for protein selection. These experiments yielded 69 proteins in common with those identified by anti-phosphotyrosine antipY ; affinity selection and these are shaded gray in Table 1 and thioguanine.

Cells 3 x 106 ; grown in complete RPMI-1640 were washed twice with thiamin-free RPMI and resuspended into the same medium supplemented with 30 nM [3H]-thiamin. After one week of exponential growth, cells were harvested, washed twice with ice-cold HBS and processed for intracellular tritium as described for transport studies.

Tion of the low thiamin dose 0.5 M ; in folate-deficient rats, compared to controls, was consistently seen at a number of dif ferent time intervals figs. 2 and 3 ; . These composite considerations suggest that dif ferences in substrate concentration and fluid and electrolyte shifts between the folate-deficient and control groups are not a likely explanation for depressed absorp tion of low concentrations of thiamin from the gut in the low folate rats. The impairment of low dose thiamin ab sorption from the intestine of folate-de ficient rats, which clearly increased with the duration and degree of folate depletion and was fully reversible with folate reple tion, was the principal new observation.

In the method of Kline and co-workers '32-'33 ; , the entire cereal and casein portion of the diet is subjected to autoclaving. Experiments were made with a diet similar to that described by Kline and co-workers. It was found that polyneuritis was readily produced on the basal diet, and that polyneuritic symptoms could be prevented by addition of a fullers' earth adsrbate, containing thiamin, to the basal diet. However, when the amount of fullers' earth adsrbate was increased threefold over the level which just protected against polyneuritis, growth was very slow. The chicks developed a crow-like appearance, and their crops became enlarged and hematomatous. Autoclaving is known to reduce the biological value of proteins in cereal grains Morgan and King, '26 ; . The basal diet of Kline and co-workers was later modified by Arnold and Elvehjem '38 ; to contain 2% of untreated vacuum-desiccated whole liver substance. Subsequent investi gations in the Wisconsin laboratory placed the thiamin con tent of dried beef liver at 12 micrograms per gram Mickelsen et al., '39 and timolol.
All practitioners are aware that benzodiazepines should only be used short term. Patients taking benzodiazepines are at increased risk of falls, fractures, motor vehicle accidents, decline in general function and cognitive impairment1. Many don't like to initiate benzodiazepine therapy for fear that it may lead to chronic use. Yet every practice has elderly patients who have been on benzodiazepines for "many years", usually for its anxiolytic or hypnotic effects. These and thiamin.
