Identification of four genomic loci highly related to casein-kinase-2-alpha cDNA and characterization of a casein kinase-2-alpha pseudogene within the mouse genome.

Using the coding region of the human CK-2 alpha cDNA as a probe for screening a genomic mouse library, positive clones representing four different genomic loci were isolated. Partial DNA sequences of these loci encompassing the first 120 nucleotides of the putative coding region are reported. One positive clone was further analyzed by sequencing a 3.1 kb XbaI fragment. This clone displays the characteristics of a pseudogene, i.e. lack of introns and several nucleotide insertions and deletions. In its 3' region it contains a 91 bp large CT-rich stretch which consists of (CCTT) and (CT) repeats; in the 5' region three (CCCCCT) repeats.

[Analysis of regional trends in narcotic studies between 1980 and 1986].

During the period of survey, the number of narcotic drug seizures by the law, especially cannabis resin, has increased considerably. The details on this development are presented. The following main analytical results were obtained: the median concentration of THC in cannabis resin has increased up to 8.6%, in cannabis plants the THC content has fluctuated between 1% and 3%. In the heroin samples since 1982, diamorphin has predominated in the base form; the diamorphin content had dropped to 32%, which is connected with a rise simultaneous in the concentration of noscapine (up to 9%). The concentration of cocaine hydrochloride had diminished at the end of the period to 62%; on the other hand, the amphetamine sulfate content increased to 69%. LSD trips used from 10 to 120 micrograms per trip. Methadone occurred mostly in the form of tablets containing 5 mg methadone hydrochloride.

Amphetamine

[Perfected, professional body-packing].

A 27-year-old Columbian male was arrested in Aix la Chapelle at the border to Belgium, as he was suspected, of smuggling drugs in his body. Ultrasonographic and radiographic examinations revealed numerous packets in the colon descendens and the ampulla recti. After administration of laxatives, 70 packets were excreted that had been swallowed 3 days before in Bogota, Columbia. Each packet consisted of two rubber bags that were separately knotted with cord, layers of plastic foil, two further knotted rubber bags; the pressed core of cocaine was an average 3.8 cm in length, 1.9 cm in diameter, and 10.2 g in weight. The cocaine hydrochloride content ranged from 75.7% to 100%, with an average of 81.9%. The total net weight came to 714 g. Urine analysis revealed no cocaine metabolites, but metamizole and metamizole metabolites were present as a result of administration of Buscopan compositum during the flight to prevent premature excretion of the packets.
