$11{\alpha}$-hydroxyprogesterone hemisuccinate-BSA를 항원으로 하여 항원량을 $50{\mu}g/head$ 및 $100{\mu}g/head$의 2 group(세마리씩)으로 나누어 BALB/c mouse에 면역첩종한 결과 후자에서 항체가의 상송이 확인되었다. 이와 동시에 항원($20{\mu}g$)과 adjuvant의 비율을 1:9로 하여 장기 접종한 결과는 $100{\mu}g$투여시 보다 항체가가 낮았다. 항체가가 확인된 clone의 culture에 의해 progesterone 단일크론 hybridoma를 생산해 이의 supernatant에 대한 분석을 실시한 결과 immunoglobulin class는 IgM이었다. progesterone 이외의 다른 steroids와의 교차반응은 매우 낮았다.

In order to estimate the human placental lactogen levels and its value as an indicator of placental function during the first half of normal pregnancy, we defermined HPL levels. in normal snbjects (No=40) from the 6th week to the 20th week of gestation For the determination of human placental lactogen in serum of normal pregnant women during the first half of prognancy, radioimmunoassay have been performed using Phadebas HPL Test kit. The range of 25ng to 800ng HPL/ml. were determined by the procedures using Phadbas HPL Test kit, which correspond to levels recorded throughout the first half of normal pregnancy. HPL was detected in the earliest pregnancy samples collected at 6 weeks but was generally present in minute amount during the first trimester of pregnancy, when the HPL level ranged from 25 ng/ml. to 0.86 ${\mu}g$/ml. The mean concentration of HPL increased gradually from only 0.03 ${\mu}g$/ml, at 6 weeks to 0.25 ${\mu}g$/ml, at 12 weeks of gestation, Subsequently the mean HPL value rose steeply from 0.25 ${\mu}g$/ml, at 12 weeks to 1.65 ${\mu}g$/ml, at 20 weeks of gestation.

난포 자극 홀몬(hFSH)을 클로라민 티를 사용하여 방사성 요오드로 표지하였으며 평균표지수율은 대략 65%이었다. 표지홀몬을 방사면역측정용으로 사용하기 위하여 전분젤 전기영동과 젤 여과법으로 분리정제하고 그 분리정제효과를 분석한 결과 젤 여과법이 분리시간, 간편성, 항체와의 결합력등으로 보아 우수함을 알 수 있었다. 한편 유리 표지홀몬과 항체와 결합한 표지홀몬의 비율을 결정하기 위하여 이중 항체법을 크로마토 전기영동법과 비교하여 본 결과 이중항체법에 의해서만 효과적 비율결정이 가능하였다.

A study was conducted to improve breeding efficiency of dairy and beef cows on Cheju Island. Milk progesterone and plasma progesterone profiles were determined by using radioimmunoassay techniques during the oestrus cycle, onset on oestrus and during the gestation period. Progesterone connections in milk were very low during the oestrus with a means value of 2.4ng/ml and 4.6ng/ml at the onset of oestrus but gradually declined at 4 to 9 hr after oestrus. In the cyclic cow, milk progesterone concentraitons in the early part of the cycle, ranged from 3 to 5ng/ml and increased from 6.0 to 11.6ng/ml on day 13 to 21 of cycle. Milk progesterone concentrations of pregnancy cows ranged from 5.0 to 40ng/ml during the gestation and grom basal line to 3.5ng/ml for nonpregnant cows. Plasma progesterone concentrations of beef during pregnancy period ranged form 3.0 to 33ng/ml and basal levels ranged from 0 to less than 2.5ng/ml for non-pregnant beef cows.

In an attempt to establish the diagnostic value of serum triiodothyronine and to correlate it with pathophysiologic mechanisms of thyroid hormones in various thyroid disorders, the author measured the serum triiodothyronine levels by means of radioimmunoassay and compared them with other thyroid function tests. This study was carried out in 152 cases with various thyroid functions; 28 cases as control, 51 cases of hyperthyroidism, 50 cases of euthyroidism and 23 cases of hypothyroidism. The results obtained were as follows: 1. The serum $T_3$ level in normal control group ranged between $131{\pm}34ng/dl$. 2. The serum $T_3$ levels ranged between $306{\pm}97ng/dl$ in hyperthyroidism $138{\pm}32ng/dl$ in euthyroidism and $60{\pm}27ng/dl$ in hypothyroidism. The significant differences between these groups were noted in this study. 3. In 5(9.9%) out of 51 cases with hyperthyoidism and 9(39.1%) of 23 cases with hypothyroidism, the serum $T_3$ were measured to be in normal range. Accordingly, the diagnostic value of the measurement of serum $T_3$ with hyperthyroidism was justifiable, but with hypothyroidism, it was less creditable than that of serum thyrotropin. 4. There was little significant difference between the diagnostic value of serum thyroxine and triiodthyronine levels in various thyroid disorders. However, $T_4/T_3$ ratio was decreased in patients with untreated hyperthyroidism because of more elevation of $T_3\;than\;T_4$. Consequently, the serum $T_3$ was more sensitive than $T_3$ in some thyroid disorders. 5. The serum $T_3$ level was much more sensitive and showed prompt shift in its level during the course of treatment on the patient with various thyroid disorders. And the measurement of serum $T_3$ was a good index for the evaluation of the thyroid function. From these results obtained, the measurement of serum $T_3$ by means of radioimmunoassay is a good way to understand the status of thyroid function with various thyroid disorders and evaluate the effects of the treatment given on these patients.

용혈 검체는 혈액검사 결과에 영향을 미치는 요인 중 하나이다. 핵의학 분야 또한 용혈 검체를 부적합검체를 분류하고 채혈실에 재 채혈을 요구하기도 한다. 이는 신속한 검사를 진행해야 하는 검사실 입장에선 장애 요소이기도 하다. 그러나 진단검사의학에서는 용혈이 각 검사 종목에 미치는 영향이 많이 알려진 반면, 핵의학에서는 용혈이 얼마나 검사 결과에 영향을 미치는지 실험을 통해 알려진 바가 없어 알아보고자 한다. 먼저, 19명의 환자에서 한 명당 각2개의 검체를 획득하고, 하나는 정상적인 혈청을 얻고, 다른 하나는 인위적으로 용혈 혈청을 획득했다. 그리고 각 종목별(AFP, CEA, PSA, CA-125, CA19-9, Thyroglobulin, Prolactin, E2, Insulin, T3, T4, TSH, FT4, TG-Ab, Anti-TPO, TBII, LH, FSH, Testosterone, PTH, DHEA-s, Cortisol, C-peptide)로 검사를 실시 한 후, 용혈검체와 정상 검체간의 결과값을 t-test를 통하여 통계적으로 유의성을 확인해 보았다. 실험 결과 키트 내 매뉴얼에 용혈검체를 사용하지 않도록 한 검사 종목 뿐만 아니라 대부분의 종목에서 용혈이 핵의학 검사결과에 영향을 미치지 않음을 알 수 있었다. 그러나, 인슐린과 C-peptide의 경우에는 용혈검체가 정상검체에 비해 통계적으로 유의하게 나타났다(P<0.05). 검체의 수가 적어 모든 검사 결과에 일반화 시킬 수는 없으나, 모든 용혈 검체를 부적합 검체로 간주하여 재채혈을 요구할 필요가 없음 또한 확인되었다. 그러므로 복잡한 핵의학 검사실의 접수 업무 개선에 도움이 될 것이라 생각된다.

Progesterone level in the seminal plasma and serum were measured by radioimmunoassay. The average level of seminal plasma progesterone was 0.76$\pm$0.15 ng/ml, similar to that of serum: 0.64$\pm$0.08 ng/ml. Progesteron levels in the seminal plasma were higher in the breeding season than in the nonbreeding season.
