INTRODUCTION

This Supplement to Aerospace Medicine and Biology (NASA SP-701 1) lists 323 reports,

articles and other documents announced during January 1974 in Scientific and Technical

Aerospace Reports (STAR) or in International Aerospace A.bstract.s (IAA 1 . The first issue

of the bibliography was published in July 1964; since that time, monthly supplements have

been issued.In its subject coverage, Aerospace Medicine and Biology concentrates on the biological,

physiological, psychological, and environmental effects to which man is subjected duringand following simulated or actual flight in the earth's atmosphere or in interplanetary space.References describing similar effects of biological organisms of lower order are also in-

cluded. Such related topics as sanitary problems, pharmacology, toxicology, safety and sur-

vival, life support systems, exobiology, and personnel factors receive appropriate attention.

In general, emphasis is placed on applied research, but references to fundamental studies and

theoretical principles related to experimental development also qualify for inclusion.Each entry in the bibliography consists of a bibliographic citation accompanied in most

cases by an abstract. The listing of the entries is arranged in two major sections: IAA

Entries and STAR Entries. in that order. The citations, and abstracts when available, are

reproduced exactly as they appeared originally in IAA or STAR. including the originalaccession numbers from the respective announcement journals. This procedure, which

saves time and money, accounts for the slight variation in citation appearances.Two indexes-subject and personal author-are included.An annual index will be prepared at the end of the calendar year covering all documents

listed in the 1973 Supplements.

All publications abstracted in this Section are available from the Technical InformationService, American Institute of Aeronautics and Astronautics, Inc. (AIAA). as follows:Paper copies are available at $5.00 per document up to a maximum of 20 pages. Thecharge for each additional page is 25 cents. Microfiche () are available at the rate of$1.00 per microfiche for documents identified by the # symbol following the accessionnumber. A number of publications, because of their special characteristics, are availableonly for reference in the AIAA Technical Information Service Library. Minimum airmailpostage to foreign countries is $1.00. Please refer to the accession number, e.g. A74-10763.when requesting publications.

STAR ENTRIES (N74-10000 Series)

A source from which a publication abstracted in this Section is available to the public isordinarily given on the last line of the citation, e.g., Avail. NTIS The following are themost commonly indicated sources (full addresses of these organizations are listed at theend of this introduction)

Avail: NTIS. Sold by the National Technical Information Service at the price shown inthe citation. If no price is shown in a current STAR citation, it may be ascertainedby referring to Government Reports Announcements or to NTIS. Beginning withdocuments announced in Issue 21, 1973, "stocked" reports, such as printed NASAreports are priced on a step schedule ranging irregularly from $2.75 for a 1-to-25page report to $10.75 for 576 to 600 pages, plus $2.00 for each additional100-page increment. Demand print reports (those for which a facsimile reproductionwill be made to fill orders) are priced at $3.00 for the first 20 pages plus 25 centsfor each five pages or portions thereof. These prices are not applied retroactively;i.e., reports previously announced at a certain price continue to be sold at thatprice. If "Avail: NTIS" without a price appeared in the citation of a NASA report(asterisked) it is sold at $3.00 whether printed copy or facsimile is supplied.Because of price changes and possible surcharges, it is recommended that for anydocument announced in STAR before July 1970, NTIS be queried as to the price.Document prices are subject to change without notice. See "Avail: SOD" below fordocuments available from both the Superintendent of Documents and NTIS.Microfiche. Microfiche is available from NTIS at a standard price of $1.45(regardless of age) for those documents identified by the # sign following theaccession number (e.g., N74-10108#) and having an NTIS availability shown in thecitation. Standing orders for microfiche of (1) the full collection of NTIS-availabledocuments announced in STAR with the # symbol, (2) NASA reports only (ident-ified by an asterisk (*)), (3) NASA-accessioned non-NASA reports only (for thosewho wish to maintain an integrated microfiche file of aerospace documents by the"N" accession number), or (4) any of these classes within one or more STARcategories, also may be placed with NTIS at greatly reduced prices per title (e.g..45 cents) over individual requests. Inquiries concerning NTIS Selective Categoriesin Microfiche should be addressed to the Subscription Unit. National TechnicalInformation Service.Deposit Accounts and Customers Outside U.S. NTIS encourages its customersto open deposit accounts to facilitate the purchase of its documents now thatprices vary so greatly.NTIS customers outside the United States are reminded that they should add thefollowing handling and postage charges to the standard or announced prices:

Seven male college students, whose ages ranged from 18 to 24years, were subjected to 8 weeks of interval training followed by 12weeks of inactivity and intermittent exposure to 4,572 m. The data

IAA E SN TRIE presented indicate that intermittent exposure to hypoxia may act insome degree as an antithesis to deconditioning. This is evidenced bythe ability of hypoxia to maintain a lower pulmonary ventilation,lactic acid production, and heart rate during submaximal workfollowing training. While the data are not conclusive they do lendsome support to the use of hypoxia as an antideconditioning agent.

Previous studies have shown that glycogen and triglyceridestores in skeletal muscle are depleted during muscular work. Itseemed possible, therefore, that measurements of the concentrationsof these substrates, as indicators of prior contractile activity, mightprovide some information regarding the degree of involvement,relative to each other, of three types of muscle fibers in exercise ofvarious intensities. The three types include white fibers, red fibers,and intermediate fibers. The time course of depletion of substratestores was determined during an exercise session. G.R.

A study on human umbilical arteries was initiated to investigatethe effect of oxygen concentration as well as sodium cyanide and2,4-dinitrophenol on responses to serotonin. It was found thathuman umbilical arteries responded in a manner similar to thatpreviously observed for human umbilical veins in the presence ofmetabolic inhibitors, but maximal response of arteries to serotonin atlow oxygen partial pressure was significantly less than that observedwith the umbilical veins. The results indicate that the response toserotonin is augmented in a linear fashion as oxygen partial pressureis increased within the physiological range. G.R.

A study was conducted to assess the influence of bothprolonged cold storage and acute temperature changes on vascularresistance and on drug responses. It was found that acute changes intemperature had little effect on the resistance of perfused, isolated,small arteries. However, on comparing the resistance of fresh andrefrigerated vessels, it was found that the resistance of the freshvessels was significantly less than that of the refrigerated vessels at alltemperatures below 37 C, but not at temperatures above 37 C.
