BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agent for testing gastric emptying function, which enables a general clinician to perform a gastric emptying function test which is safe and easy to carry out, and objectively judges a decrease in gastric emptying function. In addition, the purpose is to have the patient understand the condition of the disease and to use it for diagnosis and treatment with the patient's confidence.

2. Description of the Related Art In recent years, attention has been paid to a decrease in gastric emptying function as a cause of stomach leaning, heartburn, anorexia, etc., and various methods have been tried as tests for objectively evaluating the function. Conventional representative gastric emptying function test methods include the direct isotope method and the indirect acetaminophen method. As a direct method, a radiopaque marker is used.
A method of examining the gastric emptying function by using the method has also been attempted.

However, the above-mentioned isotope method uses radioisotopes, so that the management is complicated, the gamma camera used for measurement is expensive, and its use is limited to specialized facilities. Would. On the other hand, in the acetaminophen method, it is necessary to take acetaminophen, which is an antipyretic agent, in a normal dose or more, and liver damage and the development of drug allergies are expected. Furthermore, since it is an indirect method, it is easily affected by absorption in the small intestine, metabolism in the liver, excretion from the kidney, and the like. The test target is also limited to the fluid test meal. Ultrasonic methods also require that the inspector be skilled. Because of these problems, the conventional gastric emptying function test has not been widely used in general clinical settings. Furthermore, the conventional radiopaque marker method is originally prepared for the purpose of examining the intestinal excretion function, and the marker itself has a minimum length of 4 mm. 0.0mm
As described above, since the solid body is usually about 1.0 cm, it is not discharged from the pylorus at the same time as food, but is discharged due to strong fasting contraction after all the food is discharged. Therefore, it was not possible to accurately test the original food discharge function.

The operation using the gastric emptying function test agent based on the above means will be described. First, the subject, such as a patient, fasts for a predetermined period of time and fastes, takes a predetermined number of gastrosoluble capsules packed with a large number of barium pills with a predetermined amount of water, and prepares a set amount of a semi-solid meal as a test meal. Ingest. The capsule taken inside dissolves in the stomach, and a large number of gastric emptying function test agents are released from within one capsule, and the released multiple test agents are mixed with the test meal and sequentially discharged from the pylorus. A prescribed amount of a foaming agent is taken with a prescribed amount of water after a prescribed period of time after taking the capsule, and immediately thereafter, abdominal plain X-rays are taken in the left lateral position and the supine front. By using the foaming agent, the position of the stomach is drawn, and the pills in the stomach are prevented from overlapping by changing the posture during imaging. The ratio of the number of test agents remaining in the stomach to the total number of internal test agents is defined as
And used as an index of the gastric emptying function.

[Specific inspection example] First, if the inspection method is standardized,
As the car, a total of 40 X-ray opaque test pills having a diameter of 2.0 mm were used, the body position was sitting, and the test meal was 250 g of white porridge. White porridge is a common diet when having gastrointestinal symptoms such as leaning. The time is determined in three hours,
Use the gastric residual rate for decoding. The white porridge used as the test meal is a retort pouch food, 250 g per pack,
Use 105kcal whole porridge. The capsule 5 used in this test is a gastrosoluble capsule made of gelatin, and the barium particles 3 having sugar (non-parel) as a core material 2 are solidified with methylcellulose 4. The pills 1 are encapsulated in capsules 5 in units of 20 pills. The subject was fasted for 12 hours before the test, and 20 test pills 1
Of the stomach-soluble capsules 5 packed with 30 cc of water and taking 250 g of white porridge as a test meal. The capsule 5 taken orally dissolves in the stomach and has a diameter of 1.0
Twenty barium particles of mm to 3.2 mm, preferably 2.0 mm, are released, and a total of 40 pills are mixed with white porridge and are sequentially discharged from the pylorus. After 1 hour (FIG. 5), 2 hours (FIG. 6), and 3 hours (FIG. 7) of the capsule, 4.0 g of a foaming agent was orally administered with 30 cc of water, and immediately thereafter, a plain abdominal X-ray was taken, and the left lateral recumbent side view And shoot in front of the supine. By using the foaming agent, the position of the stomach is drawn, and the pills in the stomach are prevented from overlapping by changing the posture during imaging. The ratio between the number of pills remaining in the stomach and the total number of oral pills is expressed as a percentage in the stomach and is used as an index of the gastric emptying function.

32.3%, 3-hour value 11.0 ± 9.4%, with a linear decrease observed after a 1-hour lag phase (FIG. 1). If cisapride was administered prior to the test, the gastric survival rate was 60.4 ± 24.4% for 1 hour and 5.4 ± for 2 hours.
5.5%, the value at 3 hours was 2.1 ± 3.0%, which was significantly decreased at 1 hour and 2 hours, and promotion of the excretory function was observed (FIG. 2). In contrast, when scopolamine butyl bromide was administered before the test, the gastric residual rate was 95.6 ± 4.8% for 1 hour, 86.3 ± 14.8% for 2 hours,
The 3-hour value was 56.9 ± 42.0%, which was significantly increased at the 2-hour value, indicating a decrease in the discharge function (FIG. 3). In addition, in patients with symptoms such as anorexia and leaning, the gastric survival rate was 99.2 ± 1 hour, 2 hours, and 3 hours.
Both were significantly increased to 1.2%, and it was proved that the cause of the symptoms was a decrease in the excretory function (FIG. 4). In addition, a normal range is set as a diagnostic criterion with an average of ± 3 SD, and a gastric emptying function decrease is diagnosed when a 3-hour value is 40% or more.

Since the present invention has the above-described structure and operation, the inspector does not need to be skilled and can be carried out in a general clinic as long as the facility has an X-ray imaging apparatus. As for safety, there are no complications due to tests, and it is safe for patients with liver and kidney disorders. Invasion is exposed to X-rays, but is within the range of abdominal plain radiography. Efficacy can be said to be useful for the diagnosis and treatment of gastric emptying decline because gastric emptying can be quantitatively and objectively evaluated over time. In addition, since it is non-invasive, it does not cause pain to a subject such as a patient. Therefore, anyone with a facility having an X-ray imaging apparatus can safely and easily perform measurement anywhere, and can easily grasp the gastric emptying function visually. Persuasive. Furthermore, because of the direct method, it accurately reflects the emptying function of the stomach, is excellent in sensitivity, specificity, and reproducibility, and can reduce the cost of the test at a low cost. In contrast to non-ulcerdyspepsia as a symptom group, we have established a concept of "hypergastric emptying" as a syndrome that focuses on dysfunction, and a general method of examining gastric emptying function that is useful for diagnosis and treatment. Will meet urgently needed expectations, including insurance adaptation. further,
Barium pills can safely and easily measure the decrease in gastric emptying function, obtain the patient's understanding of the condition, and actively receive a test. It is of new benefit in the diagnosis and treatment of "hypotenosis".
