Mt. Kenya, Kenya - 1982

There is something very special leaving UK in January and travelling to the equator. Twenty members thoroughly enjoyed the Kenyan highland experience and in the game parks afterwards.

On the mountain we saw colobus and sykes monkeys and, after traversing the vertical bog, hyrax, lobelias, and senecios. Our research projects included a comparison of acetazolamide and a more potent, lipophilic, carbonic anhydrase inhibitor, methazolamide for the prevention of acute mountain sickness (AMS) during a trek to the hut at 4790m just below Point Lenana (4985m). AMS was prevented equally well, blood gases were not different and side effects were similar. At 3600m methazolaminde showed a more rapid rise in PaO2 on acute therapy.

The Times summed up the depressed feeling in the UK at the time and the results of our expedition with a brilliant cartoon by Calman. Albuminuria studies and plasma lactate measurements were included and AMS scoring was compared using interviews, peer review and self-completed questionnaires.
