10 THE LETHBRIDGE HERALD Pollution threatens game fish EDMONTON (CP) A provincial government report says Edmonton sewage pollutes the North Saskatchewan Hirer as far downs Irani ;ls CJO threatening game fish such as goktcvc, pike and wallevr. Research biologist Paul Pael-kau of the Alberla Fish and Wildlife Division said pollution from municipal and industrial effluents ma> be getting worse. The division's chief fisheries biologist, Martin Paetz, said the pollution threatens game fish, but so far there have been no indications of declinging fish populations. He said the river is more prone to pollution that the Bow River through Calgary, for example. Edmonton is farther from the mountains so the river is slower and takes longer to rid itself of pollutants. Mr. Paetkau's report showed the content in the North Saskatchewan of a number of organisms associated with clean water are almost nil for up to 40 miles downstream from Edmonton. The river did not recover from the pollutants for about 90 to 100 miles downstream. The report showed the North Saskatchewan to be the most polluted of four Alberta rivers studied the Bow River downstream from Calgary, the Old-man River near Lethbridge and the Red Deer River near Red Deer. The other three were found cleaner than in a similar study a year ago; there was no significnat change in the North Saskatchewan from astounding medicine of fc Ically, to expand research into their potentials. FOUND IN 1934 And llrey are discovered in 1934 by Dr. Ulf S. von Euler of the Karolinska Institute in Stockholm, a Nobel Prize winner in medicine and physiology in 1970. Dr. von Euler back then isolated a factor from the seminal vesicles of sheep that acted to lower blood pressure, and that also produced contractions in the smooth muscle lining the uterus or womb. He coined the namo prostag-landins for a mixture of active substances produced in later research. But progress toward application had to await mainly some brilliant work by chemists to purify PC's from animal material a ton of sheep glands yielded only one 500th of an ounce of PG in order to identify it, then to make it synthetically, then to sort out and synthesize the major protaglandins in pure form. This now has been done. Closest perhaps to general use are PCs in birth control, thanks in main part to pioneering work by Dr. Sultan M. M. Karim of Makerere University School of Medicine in Uganada, and Drs. Marc Eygdeman and PCs Wigvist of the Karolinska Institute. They first used a prolaglan-din to induce labor, near a women's term. Then they used PG to induce abortions, as late as five months in pregnancy, by infusing the drug into a vein. The PCs worked in both cases by bringing about contractions of the uterus or womb, a normal event during childbirth. PCs apparently can also act to prevent a fertilized egg from becoming implanted in the wall of the uterus, or from being maintained there. Through stepping up or calming down blood pressure, other PGs show promise of becoming agents to control shock when blood pressure drops dangerously congestive heart failure, and perhaps even coronary artery disease, say recent reports to the American Heart Association. Other researchers report evidence that PG's can control the flow of gastric juices and acids, thus offering a possible way of preventing or curing stomach ulcers. Still others report indications that PGs might be useful in overcoming male sterility and in combatting arth r i t i s and to double y< SAItMA, Ont. (CP) A Sar-nia district farmer believes he can double his crop yields by taking them to the air. Doug O'Dell has abandoned his traditional farm Iractor in favor of a space-age hovercraft to fertilize and seed his fields, With a machine that doesn't touch Ihe ground, ha says he con plant and fertilize crops in all kinds of weather and at speeds up to 40 miles an hour. Mr. O'Dei; contends a tractor's slow speed and its tendency to compact the soil it travels over with its large tires hold back crop production. He says he hopes to double his production of soybeans and barley and to get 80 bushels from an acre of wheat instead of 40, using a hovercraft loaned him by an Ottawa firm for a year on an experimental basis. And, he says, he can get up to four crops a year from barley fields by seeding down with alfalfa. Travelling at half speed, 20 miles an hour, he says he crj: apply fertilizer to a 53-acre farm in half an hour. The machine is driven forward by two large fans mounted on the rear propelled by 25-horsepower motors. If is lifteo by taking in air tlirough the top of the crafts body and ejecting it out the air, mr crop Tlie Ottawa manufacturer, which had developed the machine, had never considered farm applications. Mr. O'Dell is working on attachments for spraying, fertilizing and seeding and says throttles will have to be changed from hand controls to foot pedals because tlie operator needs both hands for steering and operating the attachments. Dust clogging carburetor filters has been a problem but, says Mr. O'Dell, new fillers and the fact planting does not have to be done in rows should solve that problem. The hovercraft lifts off the ground on a cushion of air contained by a 10-inch high rubber skirt around its bottom, Tire skirt is only from one to four inches off the ground while flying, but is made of rubber soft enough not to damage crops. Mr. O'Dell says he had travelled over his soybean field "a dozen times" without harming the plants. a By ALTON BLAKESLEE Associated Press Science Editor NEW YORK (AP) PCs promise to be tomorrow's astounding new medicines, with many uses, such perfectly sale, once-a-month birth control tablet. if pregnancy had occurred, a safe drug to bring about abortion. a drug to shorten pre time a woman Is in normal labor. potent medicine to reduce high blood pressure, to boost dangerously low pressure, to pull people out of shock, or lo save them from congestive heart failure. drug to cure or prevent stomach ulcers. drug to combat the pains and swellings of arthritis. perhaps some yet unpredictable roles in human heallh.

And ghost towns lie buried roof-deep beneath the towering dunes of this moon like "thirst-land." one of tlie most terrify-ingly barren parts of the earth and also one of the richest. This is the wilderness of the Skeleton Coast, a series of mountainous dimes miles from the frontier with South Africa to the borders of Angola and sheltering the richest diamond deposits anywhere in the world. The deserted towns and settlements that once echoed to the raucous celebrating of the diamond rash years, the lonely graves of prospectors, the strange sight of a ship riding a sea of all tell of the us dunes an old digger's hut, or the bleached bones of some long-dead prospector. Here it hardly ever rains. But animals and insects survive, sometimes in strange forms, getting their moisture from the early morning dew that fleet-ingly settles on the sandy wastes. Man has given up fighting the Namib, but south of Swakop-mund, where the diamonds lie, he remains to dig his treasure from beneath the sand. Fifty or GO years ago, the desert was liltered with diamonds and all a prospector bad lo do was lo scuff through the sand and pick them up. But the diamonds no longer are there just for the picking. Ljing deep benealh the sand, they can be recovered only by using expensive, modern equipment that the great mining combines alone can poduce a physiological effect. PGs are both old and new.

Leaded gasoline spurs NRC probe WASHINGTON (API The amount of lead in the air of most major U.S. cities appar- ently has not changed signifi- cantly in the last 15 years, de- spile a rapid increase in use of leaded gasoline, says the Na- tional Research Council. A report by the council said there is 20 times as much lead in the air in metropolitan areas as in rural areas "due largely to the combustion and dispersal of lead additives in gasoline." But it said the average Amer- ican, even in the cities, "con- sumes more lead in food and beverages than he inhales from the air." However, the report said "more recent information now being developed could slightly modify" the finding, and asked for further research on the sub- ject. It also recommended in- creased monitoring of lead in common food ilenis and "more meaningful" atmospheric moni- toring "The high concentration of lead in the air of central cities conslilutes a potential health to young children and certain groups of it "but poses no Identifiable cm-mil threat lo the general population." The report was one of a series r.n atmospheric pollutants being prepared at the request of the Environment! Protection Agency. The EPA has indicated it plans to ban or limit use of lead additives in gasoline and ex- pects to make ils proposals by the end of the year. The pro- posed regulations presumably would not take effect for several years.
