In B16 mouse melanoma in culture, differentiated cells actively synthesize melanin. They are analyzed by cytological and cytochemical methods. When cultured for long periods (several months), melanogenesis is expressed according to a cyclic way, even when maintained in a culture medium of constant composition and without adding any chemical agent eventually able to influence this phenomenon. The spontaneous cyclic activity is analyseed and an explanation is given as an hypothesis. [less ▲]Detailed reference viewed: 18 (3 ULg)

After de Selys Longchamps (1842), the otter in Belgium was a widespread species along all the full of fish rivers and was regarded as a pest namely in the fishponds of the Campine. This animal becomes extremely rare now: in Wallony, we only recorded one place where cubs are reared every year. The main reasons for this steep population decrease are well known: i. the otter has been systematically destroyed by hunters, fishermen and trappers who were receiving bounties till 1965 ! ii. the water pollution and the radical changes of the rivers physical characteristics (dredging, straightening and reshaping the river beds or banks) have had disastrous effects on fish, the main food resource of the otter. iii. a lot of previous suitable habitats have been destroyed due to for example draining of swamps and marshes and concreting the river banks. A comprehensive study of the fish populations in Wallony reveals that a small number of streams are still inhabited by relatively undamaged fish communities. Most freshwaters are polluted at different levels, some in a chronic way, others irregularly and many of them have been damaged by hydraulic works so becoming unsuitable for the otters because of a drastic reduction of their fish biomass. In such circumstances it seems likely that we cannot be really optimistic as far as the otter's future in our country is concerned. The last places where otters can still be found today must be inconditionnally protected against every disturbance of whatever type; but those measures will only help if a strong program is undertaken without delay intending to improve the water quality. An educational campaign is also urgently needed. [less ▲]Detailed reference viewed: 25 (1 ULg)

Limestone formations in Belgium have always been subject to dissolution. In Devonian limestones, the oldest Belgian ones, the first karst phenomena occurred in Devonian times. Fossil caves dicovered in Devonian limestones display a Carboniferous marine fill. During Mesozoic, Dinosaurs were trapped in collapse dolines. Grints and karst depressions occurred in Tertiary times, whereas subhorizontal caves were dug out during Quaternary. To-day, in some places, swallowholes and dolines are evolving fast.

We investigated the relation between haptoglobin (Hp) phenotypes and serum levels of various biochemical markers after myocardial infarction in 496 patients. In 122 subjects selected on the basis of short delays until hospitalization, patients with Hp 2-2 had higher cumulated creatine kinase activity than patients with Hp 1-1, or Hp 2-1 (P less than 0.05), as well as higher myoglobin concentrations (P less than 0.02) 12 to 28 hours after admission. Comparison of serum enzyme activities in the remaining 374 patients confirmed that Hp 2-2 patients had significantly higher total creatine kinase, creatine kinase isoenzyme MB fraction, aspartate aminotransferase, and lactate dehydrogenase peak levels. Complications of left ventricular failure were more frequent in these patients (P = 0.05). Our results suggest that Hp 2-2 patients have more severe myocardial infarctions than Hp 1-1 and Hp 2-1 patients, However, no difference in the distribution of haptoglobin phenotype was found between patients who had a myocardial infarction and healthy subjects, indicating that Hp 2-2 does not predispose to the occurrence of infarction.
